Answer 2

Answer:

The birth rate decreased, while the death rate increased.

Explanation:

• The average population of a species decreased. This end result is only possible if the birth rate is decreased, while the death rate is increased.
• In all the different cases provided in the options, the population will grow or live in the same way.
• Populations will not continue to grow exponentially for very long. An environment can only contribute or support a limited amount of population. This limit is a constant K and is called carrying capacity. It is the maximum number of species that the environment can support or sustain.
