A
New trees are now providing constant shade, and plants around them that needed sun to survive are being overgrown by shade-dependent shrubbery.

What is an Ecological succession?

Ecological succession is the process of change in an ecological community's species composition over time. The time frame can be many decades or less or more. The cycling of nutrients like carbon, nitrogen, and sulphur is made possible by bacteria.

Ecological succession is the progressive change that occurs in a species through time as a result of the environment. Given that all biotic elements must adapt to changes in our environment, this change is both predictable and unavoidable.

The completion of this process will bring the ecosystem to equilibrium. A climax community is the one that succeeds in achieving this goal. Some species multiply in an effort to reach this balance, while others decline.

Therefore, the correct option is A.
