Sometimes due to biotic/abiotic factor the community remains in a particular seral stage (Pre climax) without reaching the climax. Do you agree with this statement. If, yes give a suitable example.

It is true that any change in the abiotic/biotic factor will arrest a particular seral stage leading to a pre-climax condition before the climax stage is achieved. This can happen in cases of forest fires, landslides, changes in soil characteristics, increase in herbivore population leading to
overgrasing.
