Answer:
b)eutrophication
Explanation:
have you ever seen a lake or body of water with a layer of green on top? That's eutrophication due to heavy amounts of growth nutrients (primarily from runoffs from agriculture) in water. Simple plants utilize those and grow very fast. As they grow, they take up the oxygen and make water oxygen poor. These produce deadzones cuz the water life basically suffocates to death due to less oxygen. Eventually plants will also die
If there is lack of water that will reduce the amount of oxygen that the place give of and it will make everything colder because of the lack in water.
The correct answer is:
Grow a legume crop to support the development of root nodule
The best way that a farmer could increase the amount of nitrogen in his fields without adding synthetic fertilizer is to grow a legume crop to support the development of root nodules. This is because legumes have a symbiotic relationship with bacteria found in the soil.
Explanation:
Legumes use nitrogen fixing bacteria, specifically symbiotic rhizobia bacteria, within their root nodules to counter the limitation.The plant root cells convert sugar into organic acids which then supply to the rhizobia in exchange, hence a symbiotic relationship between rhizobia and the legumes.
