Question 14

Four of the five answers listed below are heterotrophic.Select the EXCEPTION.
A) consumers
B) carnivores
C) herbivores
D) parasites
E) producers

Accepted Answer

Heterotrophs are organisms that cannot produce their own food and rely on other organisms for food. Consumers, carnivores, herbivores, and parasites are all examples of heterotrophs. However, producers (such as plants) are autotrophs, which means they can produce their own food through photosynthesis and are not heterotrophic.
