Carbon and Nitrogen Cycle
23
Sunlight:light and energy that comes from the Sun
Photosynthesis:plants use carbon dioxide to make their food.
Decay:Decomposing organic nitrogen into NH4+.
Carbon cycle:biogeochemical cycle.
Fossils:preserved remains or traces of animals, plants, and other organisms from the remote past
Fossil fuels:hydrocarbons.
Dead organisms:organisms ready to be decomposed into simpler matters.
Waste:synonym, unwanted, garbage.
Ocean:It contain earth's largest store of carbon.
Root respiration:exchange of gases between plant roots and the atmosphere.
Animal respiration:where the cells of internal organs are distant from the external environment, respiratory systems facilitate.
Plant respiration:passive process that occurs in all plants for the purpose of releasing energy captured and stored within the plant
Auto and factory emissions:air pollution created by people.
Coal:combustible black or brownish-black sedimentary rock.
Organic matter:matter composed of organic compounds that has come from the remains of once-living organisms such as plants and animals and their waste products in the environment.
Precipitation:the primary mechanism for transporting water from the atmosphere to the surface of the earth.
Fixation:important process in the nitrogen cycle other than ammonification, nitrification and deritrification.
Denitrifying bacteria:microorganisms whose action results in the conversion of nitrates in soil to free atmospheric nitrogen, thus depleting soil fertility and reducing agricultural productivity.
Nitrification:the process by which ammonia is converted to nitrites (NO2-) and then nitrates (NO3-).
Nitrogen fixation:NH3 / NH4+
Fertilizers:any organic or inorganic material of natural or synthetic origin that is added to a soil to supply one or more plant nutrients essential to the growth of plants.
Decomposers:organisms that break down dead or decaying organisms, and in doing so carry out the natural process of decomposition.
Soil:top layer of the earth's crust.
Nitrogen:Is the most common gas found in the earth's atmosphere.
Greenhouse effect:causing the Earth to warm up.
Carbon:pulled from the atmosphere by plants and used for the process of photosynthesis.
