Question
Drought is a weather condition that may limit the amount of water resources available to an ecosystem. Which of the following may be one result of drought? A. Fish populations may decline due to lower river levels. B. Birds may not build nests due to temperature change. C. Flowering plants may produce more seeds due to lack of water. D. Predator populations may increase due to increased prey populations.
Solution
The correct answer is A. Fish populations may decline due to lower river levels. This is because drought reduces the amount of water in rivers and streams, which can lead to a decrease in fish populations. Fish need water to survive, and if the water levels become too low, they may not be able to survive. The other options B, C, and D are not typically results of a drought. Birds can still build nests in a variety of temperatures, drought typically causes plants to produce fewer seeds due to lack of water, and predator populations usually decrease during a drought due to decreased availability of prey.
