Work Step by Step
The type of growth in which the population grows rapidly without a decline is referred to as exponential growth. The presence of sufficient amount of food resources, reduced competition, and favorable environmental conditions are some of the reasons to promote exponential growth of a particular species. So, as there is a rapid growth, it is considered to be exponential.
