What are some factors that might stop a populations exponential growth ?

All limiting factor such as food, shelter, water etc.might stop a populations exponential growth

Explanation:

Every ecosystem has a carrying capacity beyond which the population in that ecosystem can not grow. It is due to the presence of limiting factor. Some of the common limiting factors with in an ecosystem are -

a) availability of food (limited food)

b) Shelter (limited space for accommodation)

c) Limited water supply

d) Competition among the species for limited resource

e) Predation etc.

hence, all the limiting factors prevent population of any organism from growing exponentially.
