Answer 1

The correct answer is option d.

Step-by-step explanation:

Rainforests help in captivating carbon dioxide and discharge oxygen on which one relies upon for survival. The captivation of carbon dioxide also assists in stabilizing the climate of the planet.

The rainforests also assist in monitoring the water cycle of the world by supplementing water to the atmosphere via the procedure of transpiration that produces clouds. The rainforests are the homes for various plants and animal species.

The rainforests help in storing water like a huge sponge. It is found that the Amazon forests alone store about half of the rainwater of the planet. In the absence of rainforests, it would become difficult to restore the water bodies, thus, resulting in widespread disease and famine.

The rainforests help to prevent soil erosion and it is found that more than 25 percent of the presently known medicines are obtained from the tropical rainforests.
