sun and nitrogen cycle

The Sun - The sun is at the center of the solar system. Its mass is about 740 times as great as that of all the planets combined. The huge mass of the sun creates the gravitation that keeps the other objects traveling around the sun in an orderly manner. ..

Nitrogen is an important structural component of many necessary compounds, particularly proteins. Atmosphere is the reservoir of free gaseous nitrogen and nitrogen compounds are found in bodies of organisms and in the soil. Living organisms cannot pickup elemental gase..

Nitrogen Cycle - Nitrogen is an essential constituent of animal and plant matter as it forms proteins, which are the building blocks of life. The ultimate source of nitrogen is atmospheric nitrogen but neither plants nor animals are capable of assim..

Nitrogen forms nearly 78% of the volume of air. Earlier, the useful significance of nitrogen was not known and it was considered to be inactive. At that time, nitrogen was considered important only because it was known to moderate the processes of respiration and combu..

We know that energy falling in one second on the unit area of the earth's surface held normal to sun's rays is called solar constant S. Experimentally, S has been found to be equal to 1388 Wm - 2 . Let R be the radius of the sun and r be the radius of earth's orbit aro..

Carbon Cycle - Carbon is found as graphite and diamond in nature. It also occurs as carbon dioxide in the atmosphere. Because of the position of its electrons, an atom of carbon can form covalent bonds with hydrogen, oxygen, nitrogen, phosphorus and other carbon atoms. Because o..

Biogeochemical Cycles - Earth is the source of matter for all living organisms, as they require several (about 40) elements for their growth and life processes. Some elements and their compounds have an important role in the living protoplasm and are required in large amounts. These nutri..

The oxidation of pyruvic acid into CO 2 and water is called Krebs cycle..
