Answer/Explanation:
Essential nutrients such as nitrogen, phosphorus, at specific moderate level are needed for the overall functionality of the aquatic ecosystem. However, when excess of these elements infiltrates the aquatic ecosystem, the nutrient overload causes a surge in the growth of aquatic plant. For example, algal bloom. These increased growth of aquatic plant further takes up space and oxygen, prevents sunlight and later leads to what is known as "dead zone". It is a condition of an ecosystem having little or no biological activity. Aquatic life is impacted negatively when this occurs.
These are the changes that occurs as a result of nutrient loading.

Sorry for the wait.. I hope I got them all right :)
Less tilling thanks to genetically modified herbicide-tolerant crops also means that farmers spend less time on their tractors, using less fuel and reducing carbon emissions. Conservation tillage enabled by genetically modified crops has reduced greenhouse gas emissions on farms globally and can help farmers adapt to and mitigate climate change. In fact, in 2014 5.2 billion pounds of atmospheric carbon dioxide emissions were reduced by conservation tillage and decreased fuel use made possible by genetically modified crops. That’s equal to removing nearly 10 million cars from roads for one year.
According to the USDA, adopting conservation tillage can save at least 3.5 gallons of fuel per acre for farmers who would spend less time on their tractors, reducing emissions. If all of the corn planted in the U.S. (non-genetically modified and genetically modified combined) in 2015 was grown with conservation tillage methods, nearly 308 million gallons of fuel would be saved, equivalent to preventing 6.9 billion pounds of carbon emissions.
this is y air is important
Answer:
With a warm front, boundary between warm and cold air is more gradual than that of a cold front, which allows warm air to slowly rise and clouds to spread out into gloomy, overcast stratus clouds. Precipitation ahead of a warm front typically forms into a large shield of steady rain or snow.
