Answer:
Option (D)
Step-by-step explanation:
The existence of a good and favorable ecosystem depends upon certain factors such as temperature, rainfall, and sunlight. In a place where there is abundant rainfall, sunlight and moderate temperature, there occurs an ecosystem that is rich in a variety of species as it provides the necessary elements that support the existence of a favorable ecosystem. Due to the moderate temperature and good amount of precipitation, the soil in this ecosystem gets the required nutrients that help in the growth of different species of plants and trees. This given condition reflects a tropical type of ecosystem where there are numerous trees and also a huge variety of species exists. The tropical ecosystem lies in the equatorial and near-equatorial region on earth.
Hence, the correct answer is option (D).
