Question

Describe how human activity is altering the carbon cycle and the nitrogen cycle? What ecosystem service is this alteration disrupting?

Answer 1

Answer:

Human activities that affect and altering carbon cycle are

• Consuming non renewable energy sources – when oil and coal is burned carbon is released in to the atmosphere at a quicker rate than it is expelled, resulting in increase in concentration of carbon dioxide.
• Carbon sequestration when plants expel carbon dioxide from air and store it, the procedure is called sequestration. Farming and forestry service strategy can impact how mush carbon dioxide is expelled from atmosphere and store in plants. Human action in overseeing farmland impact the amount of carbon dioxide expelled from environment by plants and trees. These sinks of carbon dioxide influence the carbon cycle by diminishing carbon dioxide in air.
• Another is deforestation. Deforestation is the perpetual expulsion of trees from forests. This substantial scale expulsion of trees from forest by human results in increase dimensions of carbon dioxide since trees never again retaining carbon dioxide for photosynthesis.

Human activities that affect and altering nitrogen cycle are

• Researcher has discovered that humans are disturbing nitrogen cycle by changing the amount of nitrogen that stored in biosphere. The main reason is consuming of petroleum derivatives like vehicles, factories, power plants and other ignition process .By human activities which expands the amount of nitrogen and affect the nitrogen cycle.
• Nitrogen composts produce roughly 80 terra grams of nitrogen every year. The majority of this nitrogen is discharged in to the environment of the world and is far the biggest measure of human commitment of new nitrogen to worldwide cycle.
• Forests have the ability to hold nitrogen, in this way when trees are cut it diminish the forest capacity and increase the amount of nitrogen anticipated in the wet grounds and in air.
