question 10 of 10
an oak tree falls in a forest. it kills some ants and stops grass from growing below it. what type of disturbance is this?
a. cyclical
b. secondary
c. primary
d. small

Explanation:

A secondary disturbance occurs in an already - established ecosystem. Here, the oak tree falling affects the existing organisms (ants) and plant growth (grass) in the forest ecosystem. A primary disturbance would be something like a volcanic eruption creating new land. Cyclical disturbances follow a regular cycle, and "small" is not a standard ecological disturbance type in this context.

Answer:

B. Secondary
