Question

what is the name for a disturbance that harms some organisms, but does not hurt the ecosystem?
a. primary disturbance
b. small disturbance
c. cyclical disturbance
d. secondary disturbance

Explanation:

A secondary disturbance harms some organisms but doesn't destroy the entire ecosystem. Primary disturbance would be more severe (like a volcanic eruption creating new land). Cyclical disturbance refers to recurring events (e.g., seasonal changes). "Small disturbance" is not a standard ecological term for this concept. So, the answer is D as it fits the description of a disturbance that harms some organisms without fully disrupting the ecosystem.

Answer:

D. Secondary disturbance
