Planting additional legumes in the area shown above would most likely lead to which of the following?
A A decrease in the activity of bacteria
B A decrease in the number of animals in the area
C An increase in the activity of nitrogen-fixing bacteria
D An increase in the number of species that can fix nitrogen

C An increase in the activity of nitrogen-fixing bacteria

Explanation:

Legumes are crops e.g . Beans and they have root nodules which houses symbiotic nitrogen fixing bacteria. This nitrogen fixing bacteria helps to replace nitrogen lost as a result of previous cultivation back to the soil. Nitrogen is an important element in agriculture as it aids

Photosynthesis and useful in manufacture of protein.This is why legumes are important in crop rotation which helps to restore lost nutrients to the soil.
