A marine ecosystem is represented below (you will find the image in the attached files).
- Decomposers
6) Top carnivore: sharks, dolphins, albatross
5) Third-level carnivores: squid
4) Second-level carnivores: larger fish
3) First-level carnivores: juvenile stages of fish, jellyfish, crustaceans, and sea stars
2) Herbivore: zooplankton and cockles
1) Primary producers: phytoplankton and seaweed
- Sun provides energy to producers
What is lost to the environment at each of the trophic levels of this ecosystem?
In a trophic web, 10% of a link's energy is transferred to the following link, and the other 90% dissipates to the environment as heat. The answer is heat.
What is the trophic web?The trophic web is the interaction between different organisms involving transference of energy when some of them feed on the other ones.
The ones placed at lower levels pass energy to the ones at the higher levels.
Organisms at each level feed on the preceding one and become food for the next one.
The first link corresponds to a producer organism -autotroph-.The following links are the consumers -heter0trophs-: herbivores and carnivores.The last links are the decomposers that degrade organic matter from dead organisms.Because it is a web, all organisms are in equilibrium until a change occurs. When a sudden change affects any of the involved links, there can be a cascade effect on the web.
Any change in a link population size (increasing or decreasing) will affect the superior links and the immediately anterior link.
What is the 10% rule?From the energy that reaches the Earth's surface, only 0.1 or 1% is absorbed by autotroph organisms.
This small percentage of energy flows through all organisms in the ecosystem -from autotrophs to heter0trophs- until it dissipates in the environment.
Only 10% of energy is transferred from one level to the next one. The remaining 90% is dissipated as heat to the environment. This assessment is called The 10% rule.
This rule states that only about 10% of the energy stored as biomass at one trophic level, ends up as biomass at the next trophic level.
The progressive reduction of energy determines the number of trophic levels (4 or 5).
Heat is lost to the environment at each of the trophic levels of this ecosystem.

D. using hydroelectric dams to block rivers
Helpppp please
Answers
Answer:
The answer is A.
Explanation:
One of the downsides to electricity is the way it is generated. Usually, electricity was generated through Coal which as a fossil fuel was pivotal in releasing large amounts of carbon dioxide into the atmosphere.The method for producing electricity that has had the most negative impact on the atmosphere is A) burning fossil fuels.
What is the consequence of burning fossil fuels ?Burning fossil fuels, such as coal, oil, and natural gas, releases large amounts of carbon dioxide and other greenhouse gases into the atmosphere. These gases trap heat in the Earth's atmosphere, leading to global warming and climate change.
In addition, burning fossil fuels also releases other pollutants, such as sulfur dioxide and nitrogen oxides, which can contribute to acid rain and other environmental problems.
While all methods of producing electricity have some impact on the atmosphere, burning fossil fuels has had the most negative impact due to the sheer amount of greenhouse gases and other pollutants that are released during the process.
While there are efforts to reduce the negative impacts of burning fossil fuels, such as developing cleaner burning technologies and transitioning to renewable energy sources, the continued use of fossil fuels for electricity generation remains a significant challenge for addressing climate change and reducing air pollution.
In addition to greenhouse gas emissions, burning fossil fuels also produces other pollutants, such as sulfur dioxide and nitrogen oxides, which can contribute to acid rain and other environmental problems.
Therefore, extraction, transportation, and storage of fossil fuels can also have negative environmental impacts, such as oil spills, groundwater pollution, and habitat destruction.

When someone replicates a emotion, they tend to feel it
Nick is smiling even though he does not feel happy and after a short time he feels happier too. This change in mood is due to facial feedback. Therefore, the correct statement is option B.
What is the facial feedback mechanism?Facial feedback is a psychological theory that suggests that the expression on a face of a person can influence their emotions and mood also. Therefore, when a person smiles even when they are not feeling happy, it can trigger positive emotions in the brain that change in mood.
Nick is smiling even though he is not feeling happy. Therefore, this act of smiling can trigger positive emotions in his brain and changes his mood because of the facial feedback mechanism.
However, bottom-up processing is the processing of sensory information from the environment to create a perception, while selective encoding is a process of selectively attending to and encoding certain aspects of a stimulus while ignoring others.

3. A cell with 10 chromosomes undergoes mitosis.
(b) How many chromosomes does each daughter cell have?
Answers
Answer:
In a cell with 10 chromosomes undergoes mitosis, the result are 2 daughter cells each with 10 chromosomes
Explanation:
Cells have the ability to reproduce or replicate through 2 processes:
Mitosis
Meiosis
Mitosis differs from meiosis because the final result is always
2 daughter cells
The daughter cells are identical to the mother cell and this includes the same number of chromosomes
This means in mitosis 1 cell with 10 chromosomes leads to two identical cells each with 10 chromosomes.
