An organism that obtains organic food molecules by eating other organisms or their by-products is called what?

Explanation:
Heterotrophs rely on preformed organic molecules obtained by consuming other organisms or their by-products. They can’t fix carbon from inorganic sources themselves, so they break down the organic matter they ingest to obtain energy and building blocks. This is different from autotrophs, which make their own organic matter from inorganic sources—photoautotrophs using light energy (like plants and many algae) and chemoautotrophs using energy from chemical reactions. Examples of heterotrophs include animals, fungi, and many bacteria and protists.
