Larger trees growing in an ecosystem is an example of,

a. rapid change
b. human impact
c. extinction
d. forrest succession

The answer is D. Forrest succession

This is because the rate at which the trees grew is not given so we can't accurately say it is a rapid change. Human impact couldn't be correct because it never said humans had anything to do with it. Extinction means a large group of living things or a species dies off so that couldn't be correct either. The forest growing large trees is a successful growth of a forest. Therefore, it must be D.

Hope this helped!
