Transcript of Carbon and Nitrogen Cycles Venn Diagram

Carbon Cycle Nitrogen Cycle They both involve the ecosystem and the interaction of animals and nature Compare and Contrast the Nitrogen Cycle and Carbon Cycle Multiple ways of recycleing both nitrogen and carbon The important processes of the nitrogen cycle are fixation, mineralization, nitritfication, denitrification. Nitrogen makes up 78% of the Earth's atmosphere. Nitrogen gas is converted into ammonia by a process known as nitrogen fixation. The Nitrogen Cycle uses excretion to make NH3 (ammonia) Important processes in the carbon cycle are photosynthesis, deposition, and DECOMPOSITION. the nitrogen cycle is the set of biogeochemical processes by which nitrogen undergoes chemical reactions, changes form, and moves through difference reservoirs on earth, including living organisms. The nitrogen cycle takes place in the atmosphere, biosphere and geosphere. The carbon-nitrogen cycle is often called the CNO cycle or the Bethe-Weizsäcker-cycle Carbon dioxide is absorbed from the atmosphere by plants and algae and converted to carbohydrates by photosynthesis. Carbon is then passed into the food chain and returned to the atmosphere by the respiration and decay of animals, plants, and other organisms. The burning of fossil fuels also releases carbon dioxide into the atmosphere. The continuous process by which carbon is exchanged between organisms and the environment. The Carbon Cycle Sends particle's FROM underground or at sea level to the atmosphere. Which in turn returns the particles in the form of precipitation. The Nitrogen cycle SENDS nitrogen particle's TO the ground. Both are biogeochemical cycles and involve releasing the element in a molecular form into the atmosphere. Both begin their cycles as gasses and finish as gasses. The stages of the Nitrogen Cycle are all carried out by microorganisms. The stage of fixation in the carbon cycle is carried out by plants and animals. Humans need to interfere with the nitrogen cycle by adding nitrogen that is useful to plants.
