Question

an organism that cannot make its own food. products heterotroph autotroph reactants

Explanation:

To solve this, we analyze each term:

• "products" are the result of a chemical reaction, not related to an organism's food - making ability.
• "heterotroph" is defined as an organism that cannot produce its own food and relies on consuming other organisms.
• "autotroph" is an organism that can make its own food (e.g., plants via photosynthesis).
• "reactants" are the starting substances in a chemical reaction, not related to this biological concept.

So the term that matches the description "an organism that cannot make its own food" is heterotroph.

Answer:

heterotroph
