(b) The organisms of the third seral stage

(c) The organisms of the first seral stage

(d) The organisms of the fourth seral stage

I had been asked this question in unit test.

My enquiry is from Ecosystem in division Ecosystem of Biology – Class 12

Answer 1

Correct choice is (c) The organisms of the first seral stage

To explain I would say: The first biotic community to invade a bare land or area is known as the pioneer community. These are the organisms of the first seral stage. They further grow and expand to form a climax community.
