The Nitrogen Cycle

The Nitrogen Cycle. All life requires nitrogen-compounds, e.g., proteins and nucleic acids. Air, which is 79% nitrogen gas (N2), is the major reservoir of nitrogen. But most organisms cannot use nitrogen in this form.

The Nitrogen Cycle

The Nitrogen Cycle. Nitrogen. The most abundant element in earth’s atmosphere = approximately 78%. Used to carry out many life functions. Especially important for plant life. Nitrogen Fixation. Almost completely unusable for living things in its gaseous form (atmosphere).

The Nitrogen Cycle

The Nitrogen Cycle. All organisms need nitrogen to make proteins Nitrogen gas makes up 78% of the atmosphere, but it cannot be used directly by most organisms. Nitrogen Cycle. They get their nitrogen from substances such as ammonia that contain nitrogen .

The Nitrogen Cycle

The Nitrogen Cycle. Living things need nitrogen. It is an important element in proteins, DNA, and other chemical compounds. Nitrogen is found in fertilizers the we use in our garden and on farms. The earth’s atmosphere is 80 % nitrogen. Nitrogen Fixation.

The Nitrogen Cycle

The Nitrogen Cycle. Nitrogen forms an essential part of amino acids (which make up proteins) and DNA (hereditary material found in all living things) The movement of nitrogen through ecosystems, the soil, and the atmosphere is called the nitrogen cycle.

The nitrogen cycle

The nitrogen cycle. Why is the cycle important and what is nitrogen used for?. Not many organisms can use nitrogen directly from the air (78%) Recycling of nitrates allows plants to manufacture proteins for growth. Therefore it is a limiting factor for yield/ dry mass. 4 Main stages.
