Question
Define the biogeochemical cycle.
Answer
A biogeochemical cycle refers to the cycle of chemical elements and compounds that occur in nature and involve both biotic (living) and abiotic (non-living) components of the Earth’s ecosystem, including the atmosphere, biosphere, hydrosphere, and geosphere. These cycles are essential for the maintenance of life on Earth, as they allow for the recycling and redistribution of nutrients and energy.
