Sep 14, 2024 · Biogeochemical cycle, any of the natural pathways by which essential elements of living matter are circulated from the nonliving components of the biosphere to the living components and back. The term biogeochemical is a contraction that incorporates the biological, geological, and chemical aspects of each cycle.

A biogeochemical cycle, or more generally a cycle of matter, [1] is the movement and transformation of chemical elements and compounds between living organisms, the atmosphere, and the Earth's crust. Major biogeochemical cycles include the carbon cycle, the nitrogen cycle and the water cycle.
Apr 27, 2017 · A biogeochemical cycle is one of several natural cycles, in which conserved matter moves through the biotic and abiotic parts of an ecosystem. In biology, conserved matter refers to the finite amount of matter, in the form of atoms, that is present within the Earth.
- The Water Cycle. Water is essential for all living processes. The human body is more than one-half water and human cells are more than 70 percent water. Thus, most land animals need a supply of fresh water to survive.
- The Carbon Cycle. Carbon is the fourth most abundant element in living organisms. Carbon is present in all organic molecules, and its role in the structure of macromolecules is of primary importance to living organisms.
- The Nitrogen Cycle. Getting nitrogen into the living world is difficult. Plants and phytoplankton are not equipped to incorporate nitrogen from the atmosphere (which exists as tightly bonded, triple covalent N2) even though this molecule comprises approximately 78 percent of the atmosphere.
- The Phosphorus Cycle. Phosphorus is an essential nutrient for living processes; it is a major component of nucleic acids and phospholipids, and, as calcium phosphate, makes up the supportive components of our bones.
This type of cycle of atoms between living and non-living things is known as a biogeochemical cycle. All of the atoms that are building blocks of living things are a part of biogeochemical cycles. The most common of these are the carbon and nitrogen cycles.
