During ecological succession :
the establishment of a new biotic community is very fast in its primarv phase.
the numbers and tvpes of animals remain constant.
the changes lead to a community that is in near equilibrium with the environment and is called pioneer community
the gradual and predictable change in species composition occurs in a given area
Succession -
The gradual and fairly predictable change in the species composition of a given area is called ecological succession.
- wherein
During succession some species colonise an area and their populations become more numerous, whereas populations of other species decline and even disappear.
Option 1)
the establishment of a new biotic community is very fast in its primarv phase.
This solution is incorrect
Option 2)
the numbers and tvpes of animals remain constant.
This solution is incorrect
Option 3)
the changes lead to a community that is in near equilibrium with the environment and is called pioneer community
This solution is incorrect
Option 4)
the gradual and predictable change in species composition occurs in a given area
This solution is correct
