The information in DNA and RNA is carried in the sequence of the nitrogen bases.
Nitrogen fixation is carried out by nitrogen fixing bacteria in the nodules of the roots of legumes, and in the soil.
nitrification
Nitrogen in the air is primarily in the form of nitrogen molecules (N2) with traces of other nitrogen compounds collectively called NOx. Nitrogen in the soil is in the form of nitrates, nitrites, ammonia or protein.
The nitrogen cycle is the process by which nitrogen is converted between its various chemical forms. This transformation can be carried out via both biological and non-biological processes.Nitogen fixing bacteria takes nitrogen from the air and make it available to plants.The plants take up the nitrogen and are eaten by animals.Animals use nitrogen to make proteins.Animals die and decompose, the nitrogen goes back into the soil.Denitrifiying bacteria put the nitrogen back into the atmosphere.
lightening bolts ionized air molecules and create nitrogen compounds which are then carried by rain water down to the earth. Nitrogen-fixing bacteria would be responsible for the greatest bulk of fixed nitrogen.
Nitrogen in the atmosphere is converted into nitrogen in the soil by a process called nitrogen fixation, which is carried out by a number of different types of bacteria. Some of these bacteria grow on the roots of certain plants, such as clover, alfalfa, and peanuts, and provide nitrogen to the plant and the soil. ----------------------------------------- Lightning also causes some atmospheric nitrogen to be converted into oxides of nitrogen. These dissolve in rain water and are brought to the ground in the rain.
Nitrogen Fixation Bacteria are the primary source in which Nitrogen Fixation is carried out. The bacteria changes N2 (unreactive element) into nitrogen compounds, which are soluble and can be absorbed.
Some forms of nitrogen and carbon are carried through the environment by plants and animals.
The information in DNA and RNA is carried in the sequence of the nitrogen bases.
Oxygen is carried in the solar wind, but mostly oxygen is produced by surface plant life. Nitrogen was expected to have been part of the initial ancient atmosphere, and is non-reactive (and heavy) enough that it is still present. Ozone is made from oxygen and sunlight.
