AINLIEST FOR PPL WHO GET IT RIGHT. CALCULATE: Imagine you have a five-step food chain. If 100 percent of the energy is available at the first trophic level, what percentage of energy is available at the highest trophic level? (SHOW WORK) Using your calculated numbers, explain why there is less BIOMASS at the top of the food chain.
20 percent available at the highest tropic level. There is less at the top of the food chain because it has ate things from possibly all areas of the food chain and each level is consuming from lower parts of the chain than it. So with the entire food chain eating on what the top eats there is gonna be less for the top
Meristem cells are totipotent meaning they can differentiate to any type of plant cells. Therefore they can produce a variety of plant type depending on epigenetic. However, tissue culture is derived from already differentiated cells. Therefore these cells are already determined and can only produce cell type of that plant from which they were derived.
They speed up chemical reactions. Without them you wouldn't be alive. They break down macromolecules, and also lower the amount of energy needed for a chemical reaction to happen.
