Text SolutionText solutionverified iconVerified

Nutrient cycles are called biogeochemical cycles because ions/molecules of a nutrient are transferred from the environment (rocks, air and water) to organisms (life) and then brought back to the environment in a cyclic pathway. The literal meaning of biogeochemical is BIO- living organism and GEO- rocks, air and water.
