What happens to a population if its growth exceeds its carrying capacity?

a. it starts to grow exponentially.
b. it starts to grow logistically.
c. it stops growing.
d. it declines slowly.
d. it crashes.

Option D

Explanation: Every organism follows a growth curve to complete its life cycle. When the organism exceeds its carrying capacity in the environment, then the population crashes.

There are mechanism present in the environment to prevent growth after a certain extent of time. Example: Plants only have the ability to regenerate after being crashed but other organism lack this property.

After a certain extent, population crashes along with its environment.

This is true. Cladistics is a way to separate animals into new species. An approach to biological classification where animals or organisms are categorized based on shared derived characteristics through tracing the characteristics of the most recent ancestor and are not present in distant ancestors.
