<h2>Answer:
</h2>
Option a) The removal of the trees and grass during construction could result in erosion of topsoil.
<h2>Explanation:
</h2>
- Plants play a vital role in an ecosystem such as they produce oxygen, food, plays an important role in hydrological cycle(water cycle) etc.
- Deforestation in simple words, is the cutting down of forests for human use such as to clear land for construction, for fuel, for making furniture etc.
- Deforestation is one of the major reason for Soil erosion.
- Soil erosion is a natural process, but it get accelerated by deforestation.
- Plants are a natural barrier to slowdown soil erosion by slowing down the water current, as running water can also be a reason for soil erosion. Roots of the plants binds with the soil tightly and prevent it from washing away by water or taken away by air. Plant growth in less nutritious soil(Lower layers of soil) is very difficult(as the top layer contains maximum nutrients).
Result: Deforestation in forests and marsh play a major role in erosion of the top layer of the soil.
