If an agricultural field is converted back to a natural prairie, which statement is true?

a) soil erosion would increase
b) increased flooding of drainage basin
c) less contaminants would flow into the drainage basin
d) more contaminants would flow into the drainage basin

The correct answer is C) less contaminants would flow into the drainage basin.

Explanation:

In the agricultural field, farmers use many types of pesticides, insecticides, urea and other chemical that drained off during precipitation into the drainage basin and ultimately goes into the river and other water bodies which results in eutrophication of water bodies.

So if an agricultural field is converted back into a natural prairie than the flow of the contamination into the drainage basin will become low because now no chemical will be used to maintain prairie. Therefore the correct answer is C.

no they are not always accurate because they can not give you a specific fortune reading they can not tell you exactly what’s gunna happen

the answer is b: 1.4 km/hr
