Trophic Levels

Definition

the energy levels in a food chain

Other Info.

-90% of energy is lost between levels -the organisms with the most energy are at the bottom -they can be shown in a pyramid

Definition

the living or once-living things that have affect an ecosystem

Examples

-person -mouse -bird

Other Info.

-they are the opposite of abiotic factors -there are many different examples in every ecosystem

the variety of genes within a breeding population

Biodiversity

Definition

the variety of organisms in a geographic area

Other Info.

importance of it: -to have a healthy environment -prevents extinction -greater crop variety -more medical research possible   Biodiversity increases closer to the equator because it is possible for more species to survive in a warmer environment.
