Transcript of Nitrogen and Carbon Cycle Venn Diagram

Nitrogen Cycle Both Carbon Cycle All organisms require nitrogen to make amino acids which in return are used to build proteins. Five stages of the nitrogen cycle include fixation, uptake, mineralization, nitrification, and dentrification. All five stages are carried out by microorganism whereas the fixation of carbon is done mainly by plants. Humans need to interfere in the nitrogen cycle by adding nitrogen in a form that's useful to plants. Ex. plant fertilizers Nitrogen gas makes up 78% of the Earth's atmosphere. The cycle starts with nitrogen-fixing bacteria, or fungi. Nitrogen can also be condensed in the air by lightning. Nitrogen gas is quite abundant. Nitrogen cannot be used by plants or animals in its gaseous form. bigeochemical cycles both cycles can transfer either carbon or nitrogen from the ocean to the atmosphere or vice versa. both undergo chemical transformation that alter the form of the molecules containing them. Nitrogen and carbon are present in all living things. both involves releasing the element in a molecular form into the atmosphere both recycle nutrients that are essential to all organisms. both begin the cycle as gases and finsihes as gases. The cycle deals with exchange of carbon between organisms. Carbon combines with oxygen (carbon dioxide) is taken in by plants during photosynthesis and releases oxygen back into the air.
Much of the carbon (as CO ) is released back to the atmosphere thrpugh the respiration of living things. Ex. human respiration The carbon cycle has four main types of processes that include biological, geochemical, mixed biogeochemical processes, and human activity. Does not require special processing by bacteria prior to plants and animals being able to use it. In human activity, when CO is released back into the atmosphere it can be harmful to the Earth's atmosphere if there's too much and can cause the Earth to warm up. This is called the Greenhouse effect. The carbon cycle is a great recycler of carbon atoms. made by: Jennifer, Mackenzie, and Chelsea
