Question

scientists predict that it will likely take hundreds of years before the area returns to a forest dominated by fir and hemlock trees. these changes are an example of which of the following? primary succession since there is soil still present the biological evolution of wildflowers, shrubs, and trees humans degrading an ecosystem by removing wildflowers the growth of an ecosystem through ecological succession

Explanation:

Ecological succession refers to the process by which the structure of a biological community evolves over time. Since there is soil present and it will take a long - time for the area to return to a forest dominated by specific trees, this is secondary succession (not primary which occurs on bare rock with no soil). The changes described are about the growth of an ecosystem through ecological succession. Removing wildflowers by humans is not an example of ecological succession but rather human - induced degradation. The biological evolution of individual species like wildflowers, shrubs, and trees is different from ecological succession.

Answer:

the growth of an ecosystem through ecological succession
