Question

Need this for homework

1.What happens when fertilizer ends up in waterways?
2. Describe eutrophication.
3. What has happened at the mouth of the Mississippi River?

Answer 1

1. When manure or fertilizers enter water, the nutrients they release stimulate microorganism growth. These microorganisms reduce the dissolved oxygen content of the water body. Without sufficient dissolved oxygen in water, fish and other animals living in water suffocate.

2. Eutrophication is the process by which water bodies are enriched with minerals and nutrients.

Sorry I don't know the answer to question 3

Answer 2

1.When manure or commercial fertilizers enter surface water, the nutrients they release stimulate microorganism growth. Without sufficient dissolved oxygen in surface water, fish and other aquatic species suffocate. The resulting dead fish and other aquatic species degrade the water quality and cause unpleasant odors.

2.Eutrophication is a significant increase of algae (microscopic organisms similar to plants) due to the greater availability of one or more growth factors necessary for photosynthesis, such as sunlight, carbon dioxide and nutrients (nitrogen and phosphorus)

3. I don't know I am way to tired sorry
