In a certain forest ecosystem, there are lions who prey on deer. The deer eat grass. Which of the following would be the consequences of the deer population increasing? The lion population would stay the same.

The plant population would decrease.
The lion population would decrease.
The plant population would increase.

The plant population would decrease.

If the deer population were to increase, they would consume more grass, leading to a decrease in plant population. This could ultimately have a negative impact on the overall health of the ecosystem. The lion population, in this scenario, would likely stay the same as they would have more prey available to feed on.
