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

The science of ecology includes which of the following levels of organization in the correct order from smallest to largest?

• populations—communities—organisms—ecosystems

• communities—organisms—ecosystems— populations

• organisms—populations—communities—ecosystems

• ecosystems—communities—organisms— populations

Match the following definitions and terms.

• Community

• 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.

• Population

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

• Biosphere

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

• Ecosystem

• An individual life form.

• Organism

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