Question

what is one way to classify mud found in an ecosystem?
○ organism
○ population
○ biotic factor
○ abiotic factor

Explanation:

Ecosystem factors are split into biotic (living) and abiotic (non-living). Mud is a non-living component of an ecosystem, so it falls under abiotic factors. Organisms are individual living things, populations are groups of the same organism, and biotic factors require life, none of which describe mud.

Answer:

D. abiotic factor
