Which of the following processes is decreased when many trees are removed from an area?
Shkiper50 [21]

Answer:

Option (C)

Explanation:

When many trees are removed from any area, the area becomes dry and gets adversely affected. Due to the lesser amount of trees, the area will evaporate more due to its dry and increasing temperature, as a result of which there will be more precipitation. This precipitation will lead to more amount of surface runoff over the area. So the transpiration will simultaneously decrease as the plants will not be able to absorb water by its roots, that regulates the overall temperature of the plant and protects it from dying.

Thus, the transpiration process is directly proportional to the number of plants and trees in any area.

Thus, the correct answer is option (C).
