Place the ecology levels of organization in proper order (smallest to largest)

• organism > population > community > ecosystem > biosphere

• community > organism > ecosystem > biosphere > population

• organism > community > biosphere > population > ecosystem

• population > biosphere > ecosystem > community > organism

Match the following definitions and terms.

• Community

• All the interacting species in an area; includes only the biotic factors and excludes the abiotic factors in an area.

• Organism

• An individual life form.

• Ecosystem

• Members of the same species that live in the same area at the same time.

• Population

• Consists of all the Earth’s biotic and abiotic factors or living and once-living things and the physical environment with which they interact; the sum of all ecosystems on Earth.

• Biosphere

• All living things and the physical environment with which they interact in a particular area; all the biotic and abiotic factors in an area.
