What human activities affect the water, carbon, and the nitrogen cycle what are the consequences
Mademuasel [1]
The nitrogen cycle is impacted by humanswhenever fertilizer is applied to farmland to help crops grow. This adds nitrates to the soil. If soil erodes, the nitrates are transported and deposited in the nearest body of water. This can cause algae to overgrow in a process called eutrophication. The lake will run out of oxygen as the algae die off and bacteria begin their decomposition.Sessile organisms are greatly affected.
