If water bodies dry up, what combined effect will occur on water birds and aquatic organisms?

Correct answer: Food, water and habitat will decrease

The direct answer is A: food, water, and habitat will decrease. A water body is not only a place containing water; it is also a living habitat where birds find food, drink, rest, hide, and sometimes breed. Aquatic organisms need water for movement, breathing, feeding, growth, and reproduction. If a pond, lake, or wetland dries, the chain is clear: water decreases first, aquatic plants and small organisms are affected, food for birds becomes scarce, shelter disappears, and survival becomes difficult. Option A correctly includes all three connected losses: food, water, and habitat. Option B is wrong because drying water bodies does not make all organisms increase in deserts; many may decline or die. Option C is wrong because habitat remains important even when it is damaged; its importance does not end. Option D is biologically false because aquatic organisms depend on water. Memory cue: dry water body means less water, less food, less shelter.
