How do human activities affect chemical cycles? Classify the following human activities under the chemical cycle which it most heavily alters. Extensive cultivation of legumes Combustion of natural gas Conversion of forestland to urban use

Solution

Combustion of natural gas -------------------------Carbon cycle.

Humans impact the carbon cycle effects the combustion of any type of all activities fossil fuel, which may include oil, coal, or natural gas.fossil fuels compressed and transformed in to fossil fuels.

Extensive cultivation of legumes -------------- Nitrogen and Phosphorus Cycles.

[For example, peanuts, soybeans, peas, beans etc], creation of nitrogen fertilisers, pollution emitted by vehicles and industrial plants, are some ways of how humans have increased the amount of nitrogen in biologically available forms.

Conversion of forest land to urban use-------------------------All cycles.

affects all aspects of the biogeochemicalcycles.
