Question

organisms that do not have the ability to produce or synthesize their own food are called... chemotrophs heterotrophs photoautotrophs auto - heterotrophs

Explanation:

Heterotrophs are organisms that cannot produce their own food. They rely on consuming other organisms or organic matter for energy. Chemotrophs use chemical energy, photoautotrophs use light to make food (like plants), and "auto - heterotrophs" is not a standard term. The key here is the definition of not being able to produce food, which fits heterotrophs.

Answer:

heterotrophs
