Question

During the process of ecological succession

• A. species diversity decreases
• B. structural complexity decreases
• C. niche becomes specialised
• D. food chain relationship becomes simple

Answer 1

The correct option is C niche becomes specialised

During succession, some species colonise an area and their population becomes more numerous whereas populations of other species decline and even disappear. Each organism has an invariably defined range of conditions that it can tolerate, diversity in the resources it utilises and a distinct functional role in the ecological system, all these together comprise its niche. Hence, niche becomes specialised during the process of ecological succession.
