As a result, the concentration of carbon dioxide in the atmosphere increases. By using the fertilizer this changes some of the plants which causes the cycle to be unbalanced. Anything and everything would burn more easily. By using the fertilizer this changes some of the plants which causes the cycle to be unbalanced. Since the mid-1900s, humans have been exerting an ever-increasing impact on the global nitrogen cycle. Thats in part why were interested in what regulates the sequestration of that carbon.. Morris, associate professor of earth and environmental sciences, is an aquatic ecosystem ecologist who studies the role of dissolved organic carbon (DOC) in lakes, streams and rivers. The other half is absorbed by oceans, watersheds and plants, as part. P: (610) 758-4487 The carbon, nitrogen, and oxygen cycles are similar because they all are biogeochemical cycles showing the continuous utilization and replacement of those three elements with the help of interactions between the living and non-living elements of the earth. A few steps taken by humans can help in maintaining the biogeochemical equilibrium in the ecosystem. Phosphorus is an important mineral nutrient needed in all ecosystems, it is used as fertilizer to hasten plant blooming as well as used in plant production, which in turn is a key element needed for animals and humans. It also is becoming in excess in the water supply, wreaking havoc on the plant life and animal life. In eating the plant, the animal then picks up the transformed atom and in turn, turns it back into carbon as they breathe. That is why these areas are called dead zones.
