write a short note on Oxygen and nitrogen cycle and diagram
Answers
The nitrogen cycle is the biogeochemical cycle by which nitrogen is converted into multiple chemical forms as it circulate:s among atmosphere, terrestrial, and marine ecosystems.Important processes in the nitrogen cycle include fixation, ammonification, nitrification, and denitrification.
Oxygen is an important element to life on Earth. t is the most common element of the humarn ody . It makes up about 65 % of the mass of the human body. Most of this is in the form of water H20 ) . Oxygen also makes up about 30 % of the arth and 20 % of the atmosphere . Oxygen is constantly being used and created by different processes on planet Earth. All of these rocesses together make up the oxygen cycle The oxygen cycle is interconnected with the carbon cycle , oxygen is used and cycled by plants and animals. Plants are the main creators of oxygen in the atmosphere hrough the process of photosynthesis. Here the ree uses sunlight and carbon dioxide to produce energy and releases oxygen. The giraffe breathes in the oxygen and then breathes ut carbon dioxide. The plant can then use this carbon dioxide and the cycle is complete.
Answer:oxygen is very obedient element on the our Earth it is found in the elemental form in the atmosphere to extent of 21% it also occur extensively in the combined form in form of carbon dioxide in The crust it is formed as a dioxide of most metal and silicon and also as a carbonate sulphate nitrate and other mineral it is also an extension component of most biological molecule like carbohydrate protein and nucleic acid and fat fat but when we talk of the oxygen cycle we are main liya fring to the circle that maintain the level of oxygen in the atmosphere oxygen is returned to a small sphere in only one major process that is photosynthesis and this form board outline of Oxygen cycle in nature
