Core Books/NCERT
The forest development in such areas is kept in check due to certain conditions including: Fire: Uncontrolled burning of grassland leads to wildfires. Hence, 2 is correct. Grazing Herbivores: Overgrazing by animals leads to desertification and removal of vegetation cover. Hence, 3 is correct. Seasonal Rainfall: Savanna regions have two distinct seasons – a wet season and a dry season. There is very little rain in the dry season. In the wet season vegetation grows, including lush green grasses and wooded areas. Hence, 4 is correct. Therefore, option (c) is the correct answer.
