Answer 1

Define ecological succession. Give four differences between seral stage and climax community during succession.

Answer 2

your answer:

Ecological succession is the process of change in the species structure of an ecological community over time. The time scale can be decades (for example, after a wildfire), or even millions of years after a mass extinction.

seral stage
1. It is transitional community which develops in an area during succession.
2. Seral community is replaced by another subsequent successional community.

3. Food chains and food webs are simple.
4. Biomass is small.
5. Diversity is of lower degree.
6. Niches are fewer and generalized.
7. Size of the individuals is small.
8. Nutrient conservation is low.

climax community

1. It is final community that develops in an area at the end of biotic succession.
2. Climax community is seldom replaced.
3. Food chains and food webs are complex.
4. Biomass is high.
5. Diversity is of higher degree.
6. Niches are many and specialized.
7. Size of individuals is large.
