The correct answer is: D.The relationship controls the population size of both species.

Explanation:

In predator-prey relationships, the population sizes of both species are typically regulated through a feedback loop. Here's how this works in the context of cheetahs and zebras:

1.Cheetah population regulation: If cheetahs hunt too many zebras, the zebra population decreases. As the prey becomes less abundant, cheetahs may have less food available, leading to a reduction in the cheetah population. This keeps the cheetah numbers in check.

2.Zebra population regulation: On the flip side, cheetahs help prevent the zebra population from growing too large by preying on them. If the zebra population grows excessively, it could lead to overgrazing, which could harm the ecosystem. The presence of cheetahs helps keep the zebra population from reaching unsustainable levels.

In this way, both predator (cheetah) and prey (zebra) populations are ke...
