Tom wants to incorporate more organic practices on his farm. He wants to enrich the nitrogen content of his soil through biologi
cal fixation without adding chemical fertilizers. Which plants are best suited for this purpose? A. marine plants such as seaweed and seagrass B. cotton plants C. flowering plants D. legumes, such as beans, peanuts, and alfalfa E. potato plants
The correct answer is B. Less arable land. Arable land is the main reason why the land is cleared. Arable land is the land that is suitable for ploughing and of sufficient quality for growing plants. So for this reason, the forests are cleared (by cutting the trees and bushes) and more land for agriculture is gained.
