How is the nitrogen cycle important to humans

Explanation:

Nitrogen cycle is one of the important biochemical cycle in nature. The element nitrogen is fixed by the soil bacteria which is available in nature in the form of atmospheric nitrogen. The atmospheric nitrogen is absorbed by the soil bacteria which converts it into forms like nitrates and nitrites which are easily absorbed by the plants. The plants use these forms for the synthesis of amino acids. These amino acids are used by the plants to synthesize their proteins.

The plants and their products are the source of proteins which are the building blocks of human body. The proteins are necessary for building up the muscle mass, renew of hair and skin, repair of injured tissues, defense against the injury, foetal development and others. Hence, nitrogen cycle is important for humans.

answer; protein;

it is to be noted that an alpha particle is an helium nucleus. so it contains 2 protons 2 neutrons and has a mass number of 4. when alpha decay particles are ejected from the nucleus it gets transformed into an atom which has atomic number less than 2 and a mass number less than 4.

an equation that could represent alpha decay is radium 226 decay of alpha particle forms radon 222.
