Which statement best describes a human influence on the biogeochemical cycles?
maksim [4K]

The statement that best describes human influence on the biogeochemical cycle is as follows: increased eutrophication caused by high levels of nitrogen and phosphorous.

<h3>What is eutrophication?</h3>

Eutrophication is the ecosystem's response to the addition of artificial or natural nutrients, mainly phosphates, through detergents, fertilizers, or sewage, to an aquatic system.

Eutrophication is one major effect of the anthropogenic activities that release inorganic nutrients such as phosphate, nitrate etc into aquatic ecosystems.

However, eutrophication has its negative impacts on biogeochemical cycle as it alters the cycling of these nutrients.

Therefore, the statement that best describes human influence on the biogeochemical cycle is as follows: increased eutrophication caused by high levels of nitrogen and phosphorous.
