This question is incomplete because the options are missing; here is the complete question:
Lions and cheetahs prey on wildebeests that graze in the grasslands of the African savanna. What likely effect would increased rainfall over several rainy seasons have on the populations of wildebeests, lions, and cheetahs?
A. All three populations would increase.
B. The wildebeest population would decrease, and the lion and cheetah populations would increase.
C. The wildebeest population would increase, and the lion and cheetah populations would decrease.
D. All three populations would decrease.
The answer to this question is A. All three populations would increase
Step-by-step explanation:
Grass, wildebeests, lions, and cheetahs are part of the same food chain and due to this a change in grasses due to rainfall will affect the other species. In this context, an increase in the rainfall is likely to increase the availability of grass because grasses thrive and develop better with more rainfall. This change would cause the population of wildebeests to increase due to an increase in the availability of food. At the same time, it is likely cheetahs and lions increase because similar to wildebeest these species will have more food available, which makes it easier to survive and reproduce. This means in this situation the three populations would increase.
