How does ecological succession occur?

Explanation: Ecological succession occurs due to the changes in physical environment and population of species. … Once the environmental conditions alter, the first species may fail to flourish and another species may thrive.

How does a study of succession explain the progress of a biotic community?

In the field of ecology, community composition changes over time. The study of succession addresses this change, which can be influenced by the environment, biotic interactions, and dispersal. This change in community composition over time is termed succession. …
