How do humans affect the oxygen cycle? | Homework.Study.com Every time something burns (combustion), more carbon dioxide is The cookie is used to store the user consent for the cookies in the category "Other. How is oxygen released in the respiration cycle? Create your account. Which human activity can decrease the oxygen? The oxygen cycle is a biological process which helps in maintaining the oxygen level by moving through three main spheres of the earth which are: Atmosphere. Donald Morrisstudies how lakes, rivers and other aquatic ecosystems absorb carbon dioxide (CO2). 7.4: Human Impacts on the Carbon Cycle - Chemistry LibreTexts (610) 758-6656 Recently, people have been causing these biogeochemical cycles to change. Plants and animals use oxygen to respire and return it to the air and water as carbon dioxide (CO2). Most of the human activities responsible for the increase in global nitrogen are local in scale, from the production and use of nitrogen fertilizers to the burning of fossil fuels in automobiles, power generation plants, and industries. When we cut down forests, make more factories, and drive more cars that burn fossil fuels, the way that carbon and nitrogen move around the Earth changes. A few steps taken by humans can help in maintaining the biogeochemical equilibrium in the ecosystem. What is the most important biogeochemical cycle? How do humans influence the different cycles of matter and energy? oxygen, forest fires would become more massive and devastating. Other causes include sewage and aquaculture, which is the growing or farming of fish, shellfish and aquatic plants. Avoid using phosphorus fertilizers and nitrogen fertilizers. 2 How does human activity affect carbon dioxide levels? What human activities produce carbon dioxide? CO2 is then taken up by algae and terrestrial green plants and converted into carbohydrates . How do biogeochemical cycles interact with each other? The burning of fossil fuels and the change of land are the two main human activities that affect the carbon-oxygen cycle.
