Question

Why is it important that farmers plant crops during the winter that improve the levels of nitrogen in the soil? a. These crops can fix nitrogen into usable nitrates. b. These crops have root nodules that contain bacteria. c. These crops produce fruit that quickly decomposes into usable nitrogen. d. These crops all use nitrogen in their specialized photosynthesis process.

Answer 1

B.

The bacterial root nodules are useful to plants, since they help fix and absorve nitrogen. When in summer, these plants are already dead, the bacteria might stay on the ground, forming the root nodules on to the next plants.
