What is population growth - 

Population growth is the increase in the number of individuals in a population or dispersed group. It is typically expressed as a percentage change in the population over a period of time.

There are two main types of population growth - Exponential and logistic.

Exponential growth occurs when a population grows at a constant rate, meaning that the number of new individuals added to the population each time period is a fixed percentage of the total population. This type of growth can be seen in ideal conditions, such as when a population has unlimited resources and no competition.

Logistic growth occurs when a population's growth rate slows down as the population approaches its carrying capacity.. The carrying capacity is the maximum number of individuals that an environment can support. This type of growth is more realistic, as all populations are eventually limited by resources and competition.

Exponential growth is often represented by a J-shaped curve, while logistic growth is often represented by an S-shaped curve.
