Final answer:
When the lion population increases and they eat more zebras, it leads to a decrease in the zebra population, causing a decrease in the lion population due to a lack of prey.
Step-by-step explanation:
In an ecosystem in Africa, when the lion population increases and they eat more zebras, it results in a decrease in the zebra population. This decrease in zebras causes a decrease in the lion population due to a lack of available prey. This is an example of a predator-prey relationship where the population sizes of predators and prey influence each other in a cyclic manner.
