NEET BIOLOGY

Detailed explanation-1: -Phosphorus and nitrogen are the two main nutrients that cause cultural eutrophication as they enrich the water, allowing for some aquatic plants, especially algae to grow rapidly and bloom in high densities.

Detailed explanation-2: -To grow, plants require nitrogen compounds from the soil, which can be produced naturally or be provided by fertilizers. However, applying excessive amounts of fertilizer leads to the release of harmful greenhouse gases into the atmosphere and the eutrophication of our waterways.

Detailed explanation-3: -An overabundance of nutrients-primarily nitrogen and phosphorus-in water starts a process called eutrophication.

Detailed explanation-4: -The most common nutrients causing eutrophication are nitrogen N and phosphorus P. The main source of nitrogen pollutants is run-off from agricultural land, whereas most phosphorus pollution comes from households and industry, including phosphorus-based detergents.

Detailed explanation-5: -High levels of nitrogen and phosphorus can cause eutrophication of water bodies.
