What are biogeochemical cycles?

Biogeochemical cycles is a collective name for the cyclic processing of certain substances through live and inanimate matters in the biological, geological and chemical systems of the Earth. Relatively rare, biogeochemical cycles occur only in atoms that can be found in organic and inorganic substances. The most common biogeochemical cycles are nitrogen and carbon cycle, followed by oxygen and hydrological or water, cycle. The nitrogen cycle begins when certain bacteria in the soil near the roots of plants combine nitrogen from the air with atoms of oxygen or hydrogen to form molecules no _{3 , nitrate or NH 3 , ammonia, ammonia, ammonia, ammonia. Herbivorem organisms feed on plants to obtain nitrogen, and all -powerful animals feed on herbivore and move nitrogen into their body. The nitrogen used is released in animal waste that eats some bacteria, allowing nitrogen release back to the air.}

Although carbon is only the fourth most abundant element in the world, it is an element that serves as a base for all living things. The carbon cycle consists of converting carbon into organic matter and then back to inorganic molecules. Plants use carbon in the form of carbon dioxide in their respiratory process during photosynthesis and create tissue. Animals obtain carbon carbonates and relax the carbon molecules into the air when breathing. When plants and animals die, carbon is released into the air when organisms oxidize the matter.

The

oxygen cycle is associated with the carbon cycle of respirations of animals and plants. The second most abundant element in the Earth's atmosphere, oxygen, is also essential for most organic materials. Oxygen is released into the atmosphere of green plants that produce them from water and carbon dioxide as a by -product of photosynthesis. Then all the animals inhale to allow their bodies to process the sugars they use for energy. In addition, the oxygen in the water is a cyclingIts water plants and animals in almost the same way as oxygen in the air moves ground life.

The last of the biogeochemical cycles, the hydrological cycle, refers to the movement of water. Over a billion tons of water cycles constantly across the ground. This cycle helps maintain energy balance. The water enters the air by evaporation at high energy points and is moved by wind to low -energy points where it is released by precipitation. Upon returning to Earth, the water not only replenishes the water supplies that animals drink and soak into the soil to use the plants.
