Detailed explanation-1: -There are several sources of excessive nutrients from human activity including run-off from fertilized fields, lawns and golf courses, untreated sewage and wastewater and internal combustion of fuels creating nitrogen pollution.

Detailed explanation-2: -The primary sources of nutrient pollution are fertilizer, animal manure, sewage treatment plant discharge, detergents, storm water runoff, cars and power plants, failing septic tanks and pet waste.

Detailed explanation-3: -Nutrient pollution is the process where too many nutrients, mainly nitrogen and phosphorus, are added to bodies of water and can act like fertilizer, causing excessive growth of algae.

Detailed explanation-4: -An overabundance of nutrients-primarily nitrogen and phosphorus-in water starts a process called eutrophication.

Detailed explanation-5: -Nutrient pollution is one of America’s most widespread, costly and challenging environmental problems, and is caused by excess nitrogen and phosphorus in the air and water. Nitrogen and phosphorus are nutrients that are natural parts of aquatic ecosystems.
