Humans can affect both the nitrogen and the phosphorus cycles in various ways. which of the following statements are true? check all that apply. minimizing the use of ammonia-rich fertilizers for crops will not add excess nitrogen to the nitrogen cycle and, as a result, will decrease the amount of greenhouse gases in the atmosphere. a decrease in phosphate-rich fertilizer runoff from golf courses will likely result in increased algae population explosions and thus upset food web dynamics in nearby waterways. constant use of phosphate-rich fertilizers will increase phosphorus availability to plants, ultimately ecosystem health in the long term.

Constant use of phosphate-rich fertilizers will help increase phosphorus availability to plants, ultimately helping ecosystem health in the long term.

Explanation:

The nitrogen and phosphorus cycle is greatly affected by the activities of humans. Most fertilizers added to sustain and improve plant life are made up of phosphorus and nitrogen compounds.

When phosphate rich fertilizers are constantly used on plants, the natural available of this compound is attenuated. More phosphorus needed for plant well-being becomes available. This translates into a better plant health.

From the other options, the use of ammonia rich fertilizers helps add more nitrogen into the ecosystem. Ammonia is a compound made up of nitrogen and hydrogen.

Increase in use of phosphate fertilizer can lead to eutrophication. Eutrophication is a nutrient enrichment process in which surface runoffs carry excess nutrient into nearby water bodies. This is leads to algae boom.
