What term describes organisms that obtain food from other organisms?

Explanation:
Organisms that obtain food from other organisms are heterotrophs. They can't make their own organic matter from inorganic sources, so they rely on consuming or absorbing molecules produced by others to meet their energy and carbon needs. This contrasts with autotrophs, which synthesize their own organic molecules. Within autotrophs, phototrophs use light energy to drive food production, while some organisms use chemical energy instead. Saprotrophs are a specific kind of heterotroph that feed by decomposing dead material from living organisms, but the general idea of obtaining food from others is captured by the term heterotrophic.
