The biomass pyramid shows the decline or steady decline in biomass from base to peak of each trophic level. Pyramids employed in ecological systems don't use fresh weight.
What is the role of biomass in ecological pyramids?The biomass that is produced by organisms at every trophic level can be measured using a biomass pyramid.
The bottom level of this pyramid is occupied by the producer, which are typically plants. Primary consumers come after the producers.
The total living biomass or organic matter present at various trophic levels in an ecosystem is represented by a biomass pyramid.
The mass of living things present at each trophic level in a given sample size is used to determine biomass. Calories per unit area or dry weight in grams are two ways to see it.
Therefore, biomass is not typically represented by pyramids in ecology.

How did Darwin's observations on the Galapagos Islands change his
preconceived views on nature and evolution?*
Answer: yes it did he figured that depending on which island the finches were on they would adapt to that island depending on resources for example on finch had a very large beak in order to crack nuts on the island because it was abundant on said island
Explanation:
Answer:His discoveries on the islands were important to the development of his Theory of Evolution by Natural Selection. On the island of galapagos, Charles Darwin discovered several species of finches. Thanks to his close observations, he discovered that the different species of finches varied from island to island
Explanation: this led to him knowing about natural selection

Glucose can be broken down without the use of oxygen through the
pathway?
What is this
Answer:
glycolysis pathway
Explanation:
The process of glycolysis does not require the use of oxygen, instead, it utilizes 2 ATP to produce a net of 2 ATP, 2 NADH + 2 H+.
Glycolysis pathway is the process through which glucose can be broken down without the use of oxygen atom.
What is Glycolysis?Glycolysis is the metabolic pathway through which conversion of glucose molecules into pyruvate molecules takes place. The free energy which is released in this process is used to form the high-energy molecules such as adenosine triphosphate (ATP) and reduced nicotinamide adenine dinucleotide (NADP). Glycolysis is a sequence of ten catabolic reactions which are catalyzed by the enzymes.
Glucose is the carbohydrate which is trapped by phosphorylation, with the help of the enzyme hexokinase. Adenosine triphosphate (ATP) is the molecules which is used in this reaction and the product of this reaction is Glucose-6-Phosphate (G-6-P), inhibits hexokinase enzyme.

Explain how cells all come from preexisting cells.
Answer: Cells don't just develop or exist out of thin air they must comefrom preexisting cells.
Explanation: As we all know from the popular cell theory cells come from pre-existing cells, but what does this mean? Scientists once thought that life spontaneously arose from nonliving things. Thanks to experimentation and the invention of the microscope, it is now known that life comes from preexisting life and that cells come from preexisting cells. Cells must divide or be reproduced by other cells. A cell can't be made any other way. At least to our current understanding that is that is why it is part of the cell theory not cell law.

Monterey Bay, on the California coast, contains a diverse and complex ecological community. A variety of seaweeds and single-celled algae make up the base of the food web. Many animals, such as sea urchins, abalone, snails, and crabs, graze on these photosynthetic organisms. Otters and small fish eat all of these primary consumers and in turn are eaten by orcas and sharks. Orcas eat many other smaller organisms, including dolphins, sea lions, harbor seals, and many kinds of fish. Sea stars prey on sea urchins, abalone, and snails, whereas octopus eat crabs, fish, and sea stars. Sea lions and harbor seals eat predominantly fish. Sea cucumbers eat dead organic matter that falls to the sea floor. Place each of the organisms in the trophic pyramid based on where it gets its energy. Each organism will be used only once even if some of the organisms consume organisms from several trophic levels. Place organisms that eat from several trophic levels at the highest possible trophic level. For instance, a shark that eats sea lions, octopus, otters, and fish would be placed at the highest trophic level on the pyramid, even though the shark eats both secondary and tertiary consumers. You are currently in a labeling module. Turn off browse mode or quick nav, Tab to items, Space or Enter to pick up, Tab to move, Space or Enter to drop.The illustration has a trophic pyramid that contains a producer level labeled trophic level one, a primary consumer level labeled trophic level two, a secondary consumer level labeled trophic level three, a tertiary consumer level labeled trophic level four, a quaternary consumer level labeled trophic level five, and a section for decomposers and detritivores. Answer Bank
The trophic web is the transference of energy through different trophic levels. TL1) algae, seaweed /TL2) urchins, abalone, snails, crabs / TL3) sea-stars, otter, fish /TL4) octopus, sea lions /TL5) orca / Detritivore) cucumbers.
----------------------------------------
The trophic web is a relationship process between different organisms, through which occurs transference of energy.
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 -heterotrophs-: herbivores and carnivores.
• The last links are the decomposers that degrade organic matter from dead organisms.
As it is a web, all organisms are equilibrated until a change occurs.
When the change affects any of the involved links, there can be a cascade effect on the web.
A change in a link population size (increasing or decreasing) will affect the superior links and the immediately anterior link.
Trophic pyramid:
The trophic web can be represented as a pyramid.
The base of the pyramid is always composed of producers, followed by primary consumers, secondary, tertiary, and so on.
Outside the pyramid and closing the cycle, we can find decomposers and detritivorous.
Now, to complete the trophic pyramid, let us analyse information provided by the statement.
We will see who feeds on who.
seaweeds and single-celled algae ⇒ photosynthetic organismssea urchins, abalone, snails, and crabs ⇒ feed on photosynthetic organismsSea stars ⇒ prey on urchins, abalone, snailsOctopus ⇒ eat crabs, fish, and sea stars Otters and small fish ⇒ eat urchins, abalone, snails, and crabs Sea lions and harbor seals ⇒ feed on fishesOrcas and sharks ⇒ feed on otters, fishes, dolphins, sea lions, sealsSea cucumbers ⇒ eat dead organic matterThe options to complete the pyramid are snail, abalone, orca, otter, single-celled algae, urchin, small fishes, seaweed, crabs, sea lion, cucumber, octopus, and sea-star.
According to the analysis we did before about who feeds on who, we will complete the pyramid.
Producers TL1 ⇒ seaweeds and single-celled algaePrimary consumers TL2 ⇒ sea urchins, abalone, snails, and crabsSecondary consumer TL3 ⇒ Sea-stars, Otters and small fishTertiary consumer TL4 ⇒ Octopus, Sea lionsQuaternary consumer TL5 ⇒ OrcaDecomposer/Detritivore ⇒ Sea cucumbers-------------------------------------------------------------
