Answer:
Enzymes allow many chemical reactions to occur within the homeostasis constraints of a living system. Enzymes function as organic catalysts. A catalyst is a chemical involved in, but not changed by, a chemical reaction. Many enzymes function by lowering the activation energy of reactions.
Explanation:
The answer would be B. The available energy would decrease from the mouse to the hawk. As the trophic level goes up the energy decreases because some of the energy is lost in the form of heat for every energy transfer. This energy being lost cannot be used by the organisms on the next level.
B) Because Hydroelectric energy does not create waste but could cause ecological impacts and flooding.
