Question

Question 3 Multiple Choice Worth 1 points) In which of the following ways do organisms play a role in the water cycle? 1. Water stored in organisms returns to the atmosphere through evapotranspiration. II. Plants take up water vapor through their roots through the process of sublimation. III. Humans deplete freshwater reserves at both the surface and groundwater levels. I only ll only I and II only I and III only Il and Ill only

Answer 1

Answer:

Option (4)- I and III only

Explanation:

Evapotranspiration is the process by which the plants after absorbing water and carbon dioxide, release the excess water back into the atmosphere. It helps in synthesizing their own food.  

The freshwater reserves on the earth's surface are constantly being exploited by humans. The groundwater is exhausted due to pumping and the surface waters are contaminated by the waste materials that are produced from the industries and factories that mix with the rivers and streams. It is also used up for the agricultural purposes

Sublimation is not a process of taking in water vapor by the roots. But it is a phase transition process from solid to gas or gas to solid.  

Hence, the correct answer is option (4) i.e I and III only.
