Question

Intermediate community between pioneer and climax communities is called as
A) Seral community
B) Biotic community
C) Temporary community
D) Ecosphere

Answer 1

Hint: The first set of species or communities that develops in a bare area in ecological succession is the pioneer community. Pioneer species facilitate succession.

Complete answer:
Pioneer community consists of a few small sized organisms. The area is hostile to pioneer communities. The community consists of hardy organisms. Life span of organisms is short. Growth is fast. It is soon replaced by the next seral community. Pioneer community is established over a previously bare area. Pioneer community consists of a few small sized organisms.

A seral community is an intermediate stage found in ecological succession in an ecosystem advancing towards its climax community. In many cases more than one seral stage evolves until climax conditions are attained. A seral community is the name given to each group of plants within the succession. A primary succession describes those plant communities that occupy a site that has not previously been vegetated.

Seral communities in secondary succession can be seen in a recently logged coniferous forest. During the first two years, grasses, heaths and herbaceous plants such as fireweed will be abundant. After a few more years shrubs will start to appear; and about six to eight years after clearing, the area is likely to be crowded with young birches. Each of these stages can be referred to as a seral communities.

Therefore, the correct option is (A) Seral community.

Note: The characteristics of seral community are,
i) Diversity if of low degree
ii) Niches are generalised and fewer
iii) Both food chain and webs are simple
iv) Biomass is small
v) The individuals are small
