What is the effect of overgrazing on grass?

Correct answer: Regrowth of grass can decrease

The direct answer is A: overgrazing can reduce the regrowth of grass. Grazing means animals eat vegetation, while overgrazing means plants are eaten more quickly or more often than they can recover. Step by step: repeated grazing removes leaves; trampling may damage roots and compact soil; the grass has less time to produce new shoots and seeds; consequently regrowth decreases and land may become degraded. Option A is correct. Option B is wrong because grass does not immediately become forest; overgrazing normally removes vegetation. Option C is wrong because overgrazing does not give grass saline water. Option D is wrong because heavy grazing clearly affects grass growth and soil. Memory cue: overgrazing means “eating faster than regrowth,” so vegetation becomes weak and sparse.
