Ecosystem Organization

Community All the populations of different species that live in a particular place

Populations Group of individuals of the same species that live in the same place at the same time

Biosphere Four Major Components Air Water Life Earth

Ecosystem A particular location on Earth distinguished by its particular mix of interacting biotic & abiotic components

Climate Long term average precipitation & temperature of a particular area

Greenhouse Effect The rise in temperature the Earth experiences because certain gases in the atmosphere trap heat from the Sun’s rays

a

Importance of the Greenhouse Effect Without it, the Earth would not be warm enough to support life

Greenhouse Gases Gases with the ability to trap heat Water vapor Carbon Dioxide Nitrous Oxide Methane

Range of tolerance Physical & chemical tolerance a population has in a given environment

Ecosystem Boundaries Subjective Yellowstone Defined Caves Lakes
