Answer
- Succession
Explanation:
The transition in the species composition of a given area is called ecological succession.
This takes place due to the change in the environmental conditions in a geographical area.
During succession, some species colonise an area and their populations become more numerous, whereas populations of other species decline and even disappear.
The time scale can be decades (for example, after a wildfire), or even millions of years after a mass extinction.
