These early studies were the inspiration for hundreds of subsequent investigations on how population sizes are regulated in a wide variety of ecosystems.

Use this lesson plan to night your students find answers to 1. These systems are comprised of a series of checks and balances between predator and prey, that tend to balance the whole.

An ecological pyramid is a graphical representation of the relationship between different organisms in an ecosystem.Each of the bars that make up the pyramid represents a different trophic level, and their order, which is based on who eats whom, represents the flow of energy.Energy moves up the pyramid, starting with the primary producers, or autotrophs, such as .
