UPSC 2013: In the grasslands, trees do not replace the grasses as a part of an ecological succession because of
(a)insects and fungi
(b)limited sunlight and paucity of nutrients
(c)water limits and fire
(d)None of the above
Attempt This Question
Not attemptedCorrect Answer: (c) water limits and fire
In grasslands, scarce soil moisture and the regular occurrence of fires kill tree seedlings before they can establish, preventing replacement of grasses; therefore the key limiting factors are water deficit and fire. Insects, fungi, nutrient or light shortages are not the primary reasons in this biome. ([compass.rauias.com](https://compass.rauias.com/upsc-prelims/environment-pyq/?utm_source=openai))
