Let's look at each answer choice:

A) Autotrophs are organisms that produce their own food. Yes, plants make their own food through photosynthesis, so A is correct.

B) Heterotrophs are organisms that rely on others for food. No, as plants make their own food, they do not seek others for sustenance, so B is incorrect.
