The capacity for growth
is a measure of the success of a population of a species.
Because there are so many interactions between individuals
and the environment, measuring how well populations
grow is often complex. Population biologists frequently
use mathematical growth models to help them study real
Population models might seem like all theory and math,
but they help us understand real ecological systems
in simpler terms. They are used for testing theories,
making predictions, and for making decisions about managing
or conserving populations of many species.
In this lesson, you'll learn more about two widely used
population growth models: exponential and logistic.
