- An important characteristic of all communities is that composition and structure constantly change orderly and sequentially in response to the changing environmental conditions.
- This gradual and fairly predictable change in the species composition of a given area is called ecological succession.
- Ecological Succession finally leads to an establishment of a relatively stable community that is in near equilibrium with the environment and is called the climax community.
- The entire sequences of communities that successively change in a given area are called seres.
- The individual transitional communities are called seral stages or seral communities.
- In the successive seral stages, there is a change in the diversity of species of organisms, increase in the number of species and organisms as well as an increase in the total biomass.
