Carbon Cycle

Know the process of the Carbon Cycle

(*something similar to this)

Are ecosystems open/closed systems?

Open system; carbon cycles around environment

List three organisms that transfer carbon dioxide to the atmosphere

animals, bacteria, fungi

What human activity contribute to carbon (the most) in the atmosphere?

Burning of fossil fuels

How is carbon recycled from dead organisms?

By saprotrophs

2 examples of saprotrophs

fungi and bacteria

Pool/sink

where carbon is stored (atmosphere, fossil fuels, organisms)

How are pools/sinks typically represneted?

By boxes

flux

how carbon is transferred from one pool/sink to another

How are fluxes typically represented?

by arrows

Give some examples of pools/sinks

Atmosphere and fossil fuels

Give some examples of fluxes

egestion, ingestion, cellular respiration, decomposition, photosynthesis, and combustion

What natural process removes the most carbon from the atmosphere?

photosynthesis

What natural process adds the most carbon from the atmosphere?

combustion
