2. Fungi can act as decomposers in the environment. Why is this important?
O A. Decomposers allow plants to ingest nitrogen through their root nodules.
O B. Decomposers break down waste and return nutrients to the environment.
O C. Decomposers feed off of weak organisms of other species, weeding them out so that they don't
reproduce.
O D. Decomposers use sunlight and carbon dioxide to generate sugars.

Animal bodies (and even plant bodies for that matter) are complex enough that life couldn't exist without enzymes. enzymes are usually large, complex biological catalysts that are expensive to make. enzymes speed up the rate of chemical reactions without being used up during the reaction (they can be reused many times). they are highly specific in the reactions they regulate. knowing what enzymes are and how they function, why does this explain why complex life forms could not exist if there were no enzymes.
