1. relating to the chemical processes and cycles that occur in living organisms and the Earth's environment, including the movement of elements like carbon, nitrogen, and phosphorus through ecosystems
Usage: scientific/technical term; commonly used in environmental science and ecology

Examples

• The carbon cycle is a major biogeochemical process that affects climate and life on Earth.
• Scientists study biogeochemical cycles to understand how nutrients move through soil, water, and air.
• Wetlands play an important role in biogeochemical transformations of nitrogen and phosphorus.
• The nitrogen cycle is a complex biogeochemical pathway involving bacteria, plants, and animals.
• Biogeochemical modeling helps predict how pollution will spread through ecosystems.
• Ocean biogeochemical processes regulate the distribution of oxygen and nutrients in marine environments.
