Chapter 29, Problem 8RQ
Summary Introduction
To review:
The process, by which nitrogen from the atmosphere finds its way into the plant bodies.
Introduction:
Nutrient cycle or biogeochemical cycles are the pathways, by which the nutrients in the atmosphere are transferred to the producers or the plants. Nitrogen is one of the most essential nutrients required for the plants to grow. But the plants cannot take the nitrogen directly from the environment like carbon dioxide (CO2). They need specialized bacteria to transfer the nitrogen from the environment to the plants.

First, a plant without a nitrogen-fixing relationship, such as corn, is planted. After the harvest, a nitrogen-fixing plant replaces the initial crop. Instead of harvesting the nitrogen-fixing plant, however, it is plowed under. The cycle continues in this manner. Why would nitrogen-fixing plants be plowed under instead of harvested? * To increase water retention. Nitrogen-fixing plants are not a food crop. To increases usable nitrogen in the soil. To decrease bacteria in the soil.arrow_forward
