Nitrogen cycle human affect
Webb7 juni 2024 · Plants use the nitrogen in the soil to grow. People and animals eat the plants; then animal and plant residues return nitrogen to the soil again, completing the cycle. What are 3 ways humans have impacted the nitrogen cycle? Many human activities have a significant impact on the nitrogen cycle. WebbThe nitrogen cycle explains the how nitrogen flows between animals, bacteria, plants, the atmosphere, and the soil on earth. The uniqueness of the nitrogen cycle is that nitrogen is the most abundant gas in the earth’s atmosphere, about 78% of all air, but it can’t be directly utilized by the animals and plants unless it is converted into usable compounds.
