Answer:
The ecosystem is adversely affected.
Explanation:
The ecosystem is adversely affected due to clearing of all trees and bird population is also adversely affected because these trees are the source of habitat for these birds. When there is large number of birds in an ecosystem so the bird population automatically increases due to the presence of more habitat for the birds so if all the trees are removed so very little population of birds left in that ecosystem and this action leads to great disturbance in the ecosystem.

The population sizes are limited by the amount of resources that are available relates the changes in populations are related to the availability of an ecosystem's resources.
C. Population sizes are limited by the amount of resources that are available.
<u>Explanation:</u>
Population regulation is a phenomenon in which the population of a species utilizing the same resources meets the limiting factors. These limiting factors limit their growth and size.
The limiting factors can be density-dependent or density-independent limiting factors. The density-dependent limiting factors cause reduction in per capita growth of a population when the size of the population living in an area grows larger than the source of food available in that area.
