According to the research, the biogeochemical cycles have been modified as a result of the use of intensive agriculture and the use of fertilizers, industrial activities and the burning of fossil fuels.
<h3>What are the biogeochemical cycles?</h3>
These are the movements of various chemical elements between organisms and the environment through different processes.
Specifically these involve a chemical change, through the production and decomposition of elements, and other substances between living beings and biomass, atmosphere and aquatic environments where humans overload ecosystems through the burning of fossil fuels and the increase in industrial and agricultural activities.
Therefore, we can conclude that according to the research, the biogeochemical cycles have been modified as a result of the use of intensive agriculture and the use of fertilizers, industrial activities and the burning of fossil fuels.
