Answer: C
Explanation:
Heterotrophs depend on living organisms to survive. The majority of plants, do NOT depend on living organisms for energy, as they use photosynthesis. Fungi, Animals, and all other non-photosynthesizing organisms depend on others energy. Not all Heterotrophs need meat, deer do not eat meat, yet they are still heterotrophs. Not all heterotrophs need 1 liter of water, the average gray squirrel needs 2 - 3 tablespoons a day. I believe the answer is C.
