Photosynthesis stores energy in complex organic molecules, while respiration releases it.
Photosynthesis & Respiration

Burning of fossil fuels (Transportation) Power generation (Heating) Volcanic eruptions Productions of cement (Limestone) Through the decay of plant and animal
matter
5 Ways carbon is released in the Atmosphere

The amount of carbon dioxide there is in the atmosphere .0387 %.
Percent of the atmosphere is CO2
Fact: With out green house gases like Carbon Dioxide trapping heat into the atmosphere, the earth would be frozen.

natural or artificial reservoir that accumulates and stores some carbon-containing chemical compound for an indefinite period
Ocean - Largest active carbon sink Forests Regenerative agriculture Soils - Short to long term carbon storage
4 Carbon Sinks

Photosythesis - Plants store and use as food and carbon dioxide to produce oxygen
Consumption - Animals consume the plants Respiration - Released back into the air Decomposition - over time becomes fossil
fuels (humans, by burning, transportation, ect.)
Chemical Reactions Involved

Short term organic - Plants and animals Long term organic - Fossil Fuels Long term inorganic - Limestone
(Carbon reservoirs are implications of global warning)
Inorganic and Organic Reservoirs

Deforestation, clearing trees and plants that absorb CO2 by photosynthesis
Burning fossil fuels and wood add large amounts of CO2
Human impact
