Which statement best describes how this ecosystem changes during primary
succession?
A. Annual plants increase as small trees decrease.
B. Shrubs and grasses increase during the middle stages.
C. All types of species disappear during the earliest stage.
D Lichens and mosses decrease during the earliest stage.

The statement that perfectly represents the transformation of the ecosystem during primary succession is that many species decrease in abundance in the final stage except mature trees. As a result, A is the correct answer.

What is primary succession?

When a new patch of land is created or exposed for the first time, primary succession occurs.

This takes place when lava cools and forms new rocks, or when a glacier recedes and exposes rocks without soil.

Primary succession starts from the beginning, when there was no life. Igneous rock, glaciers, and other natural phenomena are examples.

Thus, the correct option is A.
