Question

A stage in the sequence of communities that successively change in a given area is called a ___ .

• A. sere
• B. bioindicator
• C. population
• D. pyramid of number

Answer 1

The correct option is A sere

The gradual and fairly predictable change in the species composition of a given area is called ecological succession. During succession some species colonise an area and their populations become more numerous, whereas populations of other species decline and even disappear. The entire sequence of communities that successively change in a given area are called seres.
