Question

3. How can burning fossil fuels affect the nitrogen cycle?

Answer 1

The burning of fossil fuels releases nitrogen oxides into the atmosphere, contributing to acid rain, greenhouse gas emissions, and eutrophication.

Step-by-step explanation:

Burning fossil fuels affects the nitrogen cycle by releasing various nitrogen oxides into the atmosphere. These oxides contribute to a range of ecological problems, such as the creation of acid rain and greenhouse gases like nitrous oxide (N₂O), which can contribute to climate change. One significant consequence of the altered nitrogen cycle is eutrophication, which leads to the overgrowth of algae in water bodies, resulting in reduced oxygen levels and the death of aquatic life.

Answer 2

Sources of nitrogen from human activities, such as electric power generation, industry, transportation and agriculture, can upset the natural balance of nitrogen in the environment. When fossil fuels are burned, they release nitrogen oxides into the atmosphere, which contribute to the formation of smog and acid rain.
