Question

Identify the CORRECT statement with respect to ecological succession.

Options

• The sudden and unpredictable change in the species composition of the given area is called ecological succession.

• The process of primary succession is faster than that of secondary succession.

• All communities change their structure and composition in response to change in environmental condition.

• Secondary succession begins in an area of newly cooled lava and bare rock.

Answer 1

All communities change their structure and composition in response to change in environmental condition.

Explanation:

In an area of newly cooled lava and bare rock, primary succession begins. The primary succession process is slower than the secondary succession process. The term "ecological succession" refers to the steady and relatively predictable change in species composition.
