What types of organisms will be affected by a decreased supply of water in an ecosystem? a. producers, consumers, and decomposers will be affected. b. producers and consumers will be affected. c. consumers and decomposers will be affected. d. no organisms will be affected.

The answer is a. Producers, consumers, and decomposers will be affected.

All organisms are dependent on water, no matter what level they are in the trophic pyramid. Plants are, for example, producers. They need water to survive. Water is absorbed from the soil through the roots and transported to the other parts of the plants so it could be used in different physiological processes. Similarly, animals that are consumers and feed on the producers or other consumers, as well as decomposers, need water for normal physiological functions. 

The Correct Answer is A

Explanation:

The principal role of water is to thrust plant germination; implement a constant residence for classes that live within it, or present a substitute home or breeding territory for various amphibians, insects and other water-generated animals; and to replenish the nutrients and minerals essential to maintain physical life.
