Forest A
Forest B
Two forest communities are shown here at different stages of succession. The different plant species and their relative abundance are
indicated by the diagrams. Researchers find that rodent populations are more abundant in forest A while deer populations are more
abundant in forest B. What describes the difference in the populations observed by the researchers?
es ))
A)
Forest A has is in an earlier stage of succession and does not have as many
mature trees upon which deer feed.
B)
Forest B lacks grasses due to lower light levels at the ground, removing a
species that is toxic to most deer populations.
0)
Forest B lacks the canopy closure required for protection of rodents from
predators, which decreases the rodent populations.
D)
Forest A is at a later stage of succession, allowing for more rodents to
migrate into the area and be found at a higher abundance.
Answer:
a, forest a is correct answer

Which is evidence of climate change due to geological evolution?
gases found in the atmosphere
fossils buried in sedimentary rock
tropical plant fossils found in the jungle
fossils from ocean organisms found in what is now a desert
Answer:
Evidence from the geological record is consistent with the physics that shows that adding large amounts of carbon dioxide to the atmosphere warms the world and may lead to: higher sea levels and flooding of low-lying coasts; greatly changed patterns of rainfall2; increased acidity of the oceans 3,4,5,6; and decreased.

In the early 1900s, the Florida panther was found all over Florida. By 1967, the population had dropped to only 30 panthers statewide, and the panther was listed as an endangered species. What is the most likely reason for the decline in the panther population?
A. Florida's climate changed dramatically.
B. Panthers were hunted by humans for many years.
C. The panthers moved north into Georgia and South Carolina.
D. Alligators stopped eating other animals and started eating panthers.
Answer:
B.
Explanation:
Florida's climate itself hasn't particularly changed a bunch, but in the 20th century the population of Florida has increased. Plus D and C are easy to rule out. The easiest explanation for the panther's decline is the fragmentation of their habitat, and human interaction with the environment, not hunting per se. Good news is that the Florida panther's population has gone up to over 100!
Best of luck, and feel free to ask for any clarification.

An ecosystem that develops from barren rock is known as?
The rebuilding of an ecosystem after a natural disaster
is known as?
Explain why secondary succession is a faster process than primary succession.
Answer:
Ecological succession happens when new life takes over an environment. ... Primary succession begins in barren areas, such as on bare rock exposed by a retreating glacier. The first inhabitants are lichens or plants—those that can survive in such an environment
Ecological restoration aims to recreate, initiate, or accelerate the recovery of an ecosystem that has been disturbed. Disturbances are environmental changes that alter ecosystem structure and function. Common disturbances include logging, damming rivers, intense grazing, hurricanes, floods, and fire
Secondary succession is usually faster than primary succession because soil and nutrients are already present due to 'normalization' by previous pioneer species, and because roots, seeds and other biotic organisms may still be present within the substrate

Question 23 (6 points)
Sea Urchins are aquatic mammals that dive down to catch and eat sea urchins. Sea
urchins hunt the sea floor to catch and eat starfish. Starfish feed off of kelp forests
under the sea.
When sea otters overpopulate they clean out the sea urchins very quickly. This
allows the starfish to overpopulate and eat too much of the kelp forests.
Answer the following questions for 2 points each:
1. Name the TWO organisms that act as Carnivores in the ecosystem described
above.
2. Identify the ecological roles of the other TWO organisms.
3. Identify which of the four organisms above would be considered a keystone
species. Explain why.
Answer: 1. Sea urchins and sea otters
2. They are prey for carnivores.
3. Sea otters, star fish
Explanation:
Sea urchins and sea otters are carnivores as they eat on the flesh of starfish and sea urchins respectively.
Starfish feed on the kelp forests which are the producers in the food chain and the starfish is the primary consumer and prey for sea urchins. So, starfish and kelp forests are the prey in the marine ecosystem.
Keystone species is the one which controls the population of other inferior species in an ecosystem. Here, sea otters consume sea urchins so the population of sea urchins remained in control Starfish controls the population of kelp forest.
5. Name one crustacean that lives in the ocean, one that lives in freshwater, and one that lives on land.

Cual es el componente gaseoso que faltaba en la atmosfera primitiva y que hoy es escencial para la vida?
Answer:
El componente gaseoso que faltaba en la atmósfera primitiva y que hoy es esencial para la vida es:
El oxigeno [tex]O_{2}[/tex]Explanation:
Se tiene constancia de que en sus inicios, la atmósfera de la Tierra estaba compuesta por los gases resultantes de las diferentes erupciones volcánicas (ya que la actividad volcánica de dicha era fue demasiado alta), por lo tanto, era normal tener una atmósfera compuesta por azufre, dióxido de carbono, nitrógeno (que hoy en día es más del 70% del aire que respiramos) e incluso agua en estado gaseoso, sin embargo, la presencia del oxígeno [tex]O_{2}[/tex] era sumamente baja, casi inexistente, actualmente su presencia en el aire es de un poco más del 20% y es sumamente importante para diferentes funciones en los seres vivos, incluso los seres vivos acuáticos que se abastecen del oxígeno disuelto en el agua, esta es la razón por la cual, si tienes una pecera con peces en tu casa, debes instalarle un sistema que abastezca de oxígeno constantemente a tu peces mascota.

Why is Carbon important?
Answer:
Carbon is an important constituent of living beings. Along with Nitrogen and oxygen, carbon is one of the essential building blocks of organic life. Carbon forms about 18% of the human body. By organic here I want to stress the fact that it includes every living thing in the world including substances that are produced by living beings. Organic Chemistry, which deals with the study of carbon compounds is a vast repository of information on such compounds. Carbon is integral because of its unique ability to form four different bonds with other elements. This makes it possible for carbon to react with many other elements and form a vast array of compounds.
Hydrocarbons which again is primarily a compound of hydrogen and carbon are the source of all our fossil fuels. ( Fossil Fuels as these fuels are literally formed by fossilized organic matter)
CO2 which again is a carbon compound is responsible for keeping our earth warm and habitable by aiding the greenhouse effect. There are many other such compounds of carbon that are very useful to the earth and living beings.
To conclude carbon in itself is not as essential as its ability to form numerous compounds that are essential for life to exist.

Global warming occurs when carbon dioxide (CO2) and other air pollutants collect in the atmosphere and absorb sunlight and solar radiation.
Explanation: do you want one?
If only one species is considered the 'fittest', why do we still have so many variation among species?
Answer:
Variation occurs in species with the genes resulting in the traits and physical characteristics that make it possible for them to be among the fittest for a number of reasons:
1. Mutation
2. Recombination and
3. Migration
Explanation:
Mutations: A mutation is a deviation from the norm in a DNA sequence. It can be stimulated by errors during the DNA replication process which happens as the cell is dividing, or by exposure to ionizing radiation, chemicals, or viral infection (whether artificial or natural).
It is noteworthy that naturally, without any human intervention, the possibility of a spontaneous mutation is very low.
Recombination: This refers to the creation of new fusion of genes in the offspring that did not occur in the parents by the processes of crossing-over and independent assortment. Independent assortment meaning that the allele the gamete received for one gene was not influenced by the allele received for another gene.
Migration: Variation by migration here refers to the introduction of new genes from into one population by another. This could happen when a new population arrives at an existing one or when an existing one migrates to another population.
We can say for example that, genes from Americans have “migrated” into the population of African origin in America given the continuous immigration of Africans into America.
So in both populations, there are very fit species, but when their genes are mixed during cross-reproduction, variation arises.

What is the food eaten by the organisms used for?
Answer:
Organisms use the stored energy in food to fuel all living processes. Food is organic molecules that serve as fuel and building material for all organisms. The breakdown of food molecules enables cells to store energy and to carry out the many functions of the cell and therefore the entire organism.
Answer:
food eaten by organisms is used for energy that the organism relys on for survival.

Clownfish, sea anemone, coral, sea urchins, sponges, and parrot fish are just a few examples of the large variety of organisms that can be found in a coral reef. The coral reef and its inhabitants are suffering due to several factors such as pollution, coastal development, sedimentation and destructive fishing practices. What would be the most likely result if some of the species in the coral reef are destroyed? Other organisms would move into the coral reef area ⊝ The coral reef would be allowed to flourish without so many fish and plants living in and around it. ⊝ The coral reef would begin to deteriorate without the variety of fish and plants necessary to maintain balance. ⊝ The waters surrounding the coral reef will become cool with the decreasing number of organisms living there ⊝ CLEAR ALL ❮ PREVIOUS ... 6 7 8 9 10 11 12 13 14 15 ...
Answer: If some of the species in the coral reef are destroyed, (The coral reef would begin to deteriorate without the variety of fish and plants necessary to maintain balance)
Explanation:
CORAL REEFS is a ocean habitat that provides shelter for a variety of aquatic animals such as clownfish, sea anemone, coral, sea urchins, sponges, and parrot fish which are just a few examples of the large variety of organisms that can be found in a coral reefs. These animals are responsible for building the reefs which takes different forms and helps in maintaining balance. This habitat is important to marine life as it provides food and shelter for them.
Recently, many human activities has posed a threat to the coral reef and it's inhabitants These activities include:
--> Pollution: this is cause any agricultural run offs, Chemical and oil spills which can damage coral growth and reproduction.
--> coastal development: an unplanned coastal development has a damaging effect on the coral reef habitat.
--> Sedimentation: This can lead to increase in turbidity of coastal waters which in turn reduces light availability to the coral reef.
--> Destructive fishing practices: inadequate management of different fishing practices has led to the depletion of key reef species and habitat damage.
From the above explanation, the aquatic species found in the coral reef are responsible for building and maintaining the reef. If they are DESTROYED due to the above mentioned human activities, the reef will begin to deteriorate.

Which explains how interference is avoided between the signals that cordless phones receive and the signals that they broadcast?
Answer:
the signals have different frequency
Explanation:
The way that interference is avoided in these cases is that the signals have different frequency. Cell phone signals travel in a very specific wavelength, how often this wave repeats in a given span is called the frequency. By having these signals in different frequencies it prevents the signals from mixing with each other and instead allowing them to reach their destination intact. Otherwise, the signals would combine into a mess of uncomprehensible data, which is what we call interference.
Answer:
D.anywhere its service broadcasts and it can receive a signal.
