Definitions I
The way in which the population is spread out across a given area.
Population Distribution
The study of how and why populations change in size and how they can be managed.
Population Dynamics
When water soaks into soils, removing the minerals and nutrients and reducing their ability to support plant life.
Leaching
(Birth rate - death rate) + net migration.
Overall Population Change Equation
