CO2 (carbon dioxide) is a key component of nature's thermostat
Plants remove CO2 from the atmosphere and water to produce carbohydrates and O2 (oxygen)
Respiration produces CO2
Some carbon lies deep in the earth and is released during burning of fossil fuels
Volcanic eruptions release CO2
CO2 is dissolved in the ocean
The carbon cycle has been distributed by vegetation removal and burning fossil fuels and wood |

Term
|
Definition
Nitrogen gas is not usable by plants or animals
Nitrogen fixation - conversion of nitrogen gas to usable forms by bacteria
Other bacteria convert nitrogen compounds back to nitrogen gas
Nitrogen oxides are produced by man and are emitted into the atmosphere - ozone
Nox are a component of acid rain
Livestock waste and fertilizer runoff produce pollution containing nitrates
Algal blooms |

|
Term
|
Definition
Phosphorus is circulated from land and ocean sediments to living organisms and back
Phosphorus is most often the limiting factor for plant growth
Geologic and climatic processes cycle phosphorus among rock, water, and air
Humans intervene by mining phosphorus and by water pollution from livestock, fertilizer, and sewage |
|
|
Term
|
Definition
Much of earth's sulfur is underground in rocks and minerals
