How is nitrogen-based fertilizers related to algae bloom?

Answer 1

Runoffs can cause serious flooding and erosion, and can carry contaminants into rivers, lakes, and oceans.

Answer 2

A. Excess oxygen dissolves in water and runs off into rivers and streams, causing plant and algae populations to explode. B. Excess carbon dissolves in water and runs off into rivers and streams, causing plant and algae populations to explode. C. Excess nitrogen dissolves in water and runs off into rivers and streams, causing plant and algae populations to explode. D. Excess hydrogen dissolves in water and runs off into rivers and streams, causing plant and algae populations to explode.

Answer 3

Nitrogen-based fertilizers contain high levels of nitrate, a nutrient that can cause excessive algae growth when runoff from farms or lawns enters bodies of water. This can lead to algal blooms, which can deplete oxygen levels and harm aquatic ecosystems.

Answer 4

agricultural runoff was polluting the large rivers. Consider the farmlands in the Midwest; the Midwest from the Rockies to the Mississippi River is in the drainage basin of the Mississippi river. All the rain water as it dilutes the pesticides and fungicides used by the farmers run off. It finds its way into wells by percolating through the soil into the water table. Eventually ending up in the major rivers flowing into gulf on Mexico. For this reason the pesticide DDT is no longer allowed to be used. There are several other pesticides and fungicides that are on the do not use list.

Answer 5

Fertilizer (and pesticide) contaminates water draining from:

* Golf courses * Farms * Urban and suburban residential areas * Fertilizer and pesticide manufacturing, sales and transfer sites

Answer 6

Fertilizer contains nutrients that help crops grow, but not all of the nutrients (like nitrogen and phosphorus) are used by the crops. The ground water collects these leftover nutrients and carries them into large water bodies, these ecosystems have a natural equilibrium. The extra nutrients build up faster than the system can move back the equilibrium and like crops the nutrients foster faster growth of the plants in the water like algae

Answer 7

Farmers use artificial nitrogen based fertilizers on their land to improve their crops. However, the fertilizer is very soluble and it washes off into the rivers lakes and oceans where it also feeds the aquatic algal plants causing them to grow (bloom) unnaturally lusciously.

Answer 8

The build up of fertilizer will cause algae to grow. The algae that grows will absorb all the oxygen in the water and make all the other plants and animals in the environment die from oxygen lack. When all the oxygen is depleted the algae also dies and the environment becomes a watery wasteland. This process is called eutrophication. So don't use so much fertilizer.

Answer 9

Runoff of fertilizers may result in salinity increase to adjacent water body/ resulting in salt water intrusion.

Answer 10

Chemicals in fertilizers can runoff and hurt/kill organisms that are living in aquatic ecosystems.
