What is the difference between a heterotroph, autotroph, & decomposed?

Explained below.

Explanation:

Organisms get their food in one of two ways.

Autotrophs (or producers) make their own food using light or chemical energy. Examples of autotrophs include plants, algae, and some bacteria.

Heterotrophs (or consumers) get organic molecules by eating other organisms or their by-products. Fungi,  animals, as well as many bacteria, signify heterotrophs. Specialized heterotrophs, called decomposers break down dead organic material and wastes.
