in rocks and sediments (and dead organisms)

in the atmosphere

in the ocean

in living organisms

from eating autotrophs

from the atmosphere

from fossil fuels

by digging in the ground

Carbon moves from the atmosphere to plants.

Carbon moves from plants and animals to soils.

Carbon moves from fossil fuels to the atmosphere when fuels are burned

Carbon moves from the atmosphere into space

photosynthesis

cellular respiration

carbonic absorption

neutralization

Living things need carbon to survive

The Earth has a finite amount of carbon

Carbon is found in non-living things such as rocks, animal shells, the atmosphere and oceans

none of these

all of these

human activities

bird migrations

the water cycle

none of these impact the carbon cycle

because plants absorb carbon in photosynthesis and drain carbon from the atmosphere

because plants release carbon in the atmosphere like the faucet in a "sink"

because plants make carbon "sink" to the bottom of the Earth

because carbon is drained from plants by animals

it disappears

it decomposes

it evaporates

none of these

all of these

all of these

volcanic emissions, plant respiration, and soil respiration

the burning of fossil fuels and deforestation

ocean loss
