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.

regulation of gene expression. gene expression can be regulated by various cellular processes with the aim to control the amount and nature of the expressed genes. these regulatory proteins bind to dna and send signals that indirectly control the rate of gene expression

explanation:

clumped distribution, because you'de have all of the population gathered in a relatively small are.

it's the most common because it provides protection and a mate for reproduction

example: humans, seeweed, cattles, etc.
