Answer 1

Answer:

The correct option is a) a climax ecosystem

Explanation:

Secondary succession can be described as a succession which takes place in areas which were destroyed due to a disaster such as human activities or a flood or storm. Initially, small shrubs and bushes start to grow which are replaces by an intermediate community with time. With the passage of time, the intermediate community gets replaced by the climax community like the deciduous trees being described in the question. Hence, the correct option is a) climax ecosystem
