Question

How can the environment affect population size?

please help!!!! it's about animals in the wildlife​

Answer 1

If the environment gets polluted or treated poorly, than there will be less animals. If the environment grows a bunch of grass however, there will be more animals eating the grass which increases the population. But if they run out of grass, then the animals die.

Answer 2

The environment can affect the population size by different factors. Some examples are climate, food, space, etc. If the environment lacks any of these, the population will decrease since it will not have the necessary survival needs.
