carbon cycle

the global process by which carbon atoms are cycled throughout Earth's systems, including the atmosphere, hydrosphere, lithosphere, and biosphere

biosphere

made up of all living organisms

hydrosphere

made up of Earth's water

atmosphere

made up of the gases surrounding Earth

lithosphere

made up of rock and the Earth's crust

atmosphere and biosphere

where there is the most exchange of carbon

lithosphere

where most of Earth's carbon is stored

cellular respiration

this process adds carbon to the atmosphere

photosynthesis

this process removes carbon from the atmosphere

volcanic eruptions

this process adds carbon to the atmosphere

burning fossil fuels

this process adds carbon to the atmosphere (human caused)

deforestation (cutting down trees)

this process adds carbon to the atmosphere (human caused)

invasive species

species that enter new ecosystems and multiply, harming native species and their habitats, ex) asian carp in the Great Lakes

marine reserve

protected area where people are not allowed to fish, swim, or anchor their boats

aquaculture

the farming of fish and other aquatic species for human consumption
