Some of these measures may have to do with climate changes and others with economic development.

Understanding of the role of biodiversity in the hydrological cycle enables better policy-making. The term biodiversity refers to the variety of plants, animals, microorganisms, and the ecosystems in which they occur. Water and biodiversity are interdependent.

Every glass of water we drink has, at least in part, passed through fish, trees, bacteria, soil and other organisms. Passing through these ecosystems, it is cleansed and made fit for consumption. The supply of water is a critical service that the environment provides.

43. Which among the following is the most critical inference that can be made from the above passage?

(a) Biodiversity sustains the ability of nature to recycle water

(b) We cannot get potable water without the existence of living organisms

(c) Plants, animals and microorganisms continuously interact among themselves
