Answer 1

In an ecosystem, a heterotroph is an organism that consumes other organisms for energy.

Step-by-step explanation:

A consumer is a heterotroph. Heterotrophs are organisms that obtain their energy by consuming other organisms or organic matter. They cannot produce their own food, so they rely on consuming other organisms.

A plant, on the other hand, is an example of a producer. Producers are capable of converting sunlight, water, and carbon dioxide into food through the process of photosynthesis.

Phytoplankton can also be considered a producer as they are photosynthetic organisms that form the basis of many aquatic food chains.
