In the grasslands, trees do not replace the grasses as a part of an ecological succession because of
- insects and fungi
- limited sunlight and paucity of nutrients
- water limits and fire
- None of the above
Explanation
Option (c) is correct
- Grasses have one good trick to monopolise a place. In the dry season, the grasses dry up and cause fires, which destroy other plant species and their seeds (autogenic succession). Also, grasslands develop in regions with scanty rainfall where plant growth cannot be achieved. Though forests form the climax community in most ecosystems, in the grassland ecosystem, grasses form the climax community. This is primarily due to the influence of fire and water scarcity. Grasslands are almost irreversible once deforestation in water-scarce areas gives way to grasslands.
