The correct answer is: C.Reducing water availability for plants and animals

Droughts are characterized by prolonged periods of abnormally low rainfall, which leads to a decrease in water availability. This has significant impacts on ecosystems, including:

Reducing water availability for plants and animals: Droughts cause a decrease in the amount of water available for plant growth and for animals that rely on freshwater sources. This can lead to plant stress, reduced crop yields, dehydration of wildlife, and even death in extreme cases. Many species may struggle to survive or migrate in search of water.

The other options are less relevant to the typical effects of droughts:

A.Promoting the growth of algae in freshwater bodies: While droughts can lead to reduced water levels in lakes and ponds, they typically do not promote the growth of algae. In fact, lower water level...
