Chapter 29, Problem 8RQ
Summary Introduction
To explain:
The process of capturing of nitrogen from the atmosphere into a plant’s body.
Introduction:
Nitrogen is one of the essential macronutrient required by all living organisms. The atmosphere is the primary reservoir of nitrogen and nitrogen circulates within the ecosystem through the nitrogen cycle. The atmospheric nitrogen enters into the body of primary producers only after conversion into ammonia and nitrate. Primary producers utilize only two forms of nitrogen that are ammonia and nitrate.

- The practice of crop rotation uses nitrogen fixation to create fertile fields. 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_forwardDo plants need soil to grow? Explain.arrow_forwardDescribe how water molecules move into the plant from the soil.

- The loss of water from a plant by transpiration cools the leaf. Movement of water in transpiration requires both adhesion to the conducting walls and wood fibers of the plant and cohesion of the molecules to each other. A scientist wanted to increase the rate of transpiration of a crop species to extend its range into warmer climates. The scientist substituted a nonpolar solution with an atomic mass similar to that of water for hydrating the plants. What do you expect the scientist's data will indicate from this experiment? The rate of transpiration will be the same for both water and the nonpolar substance. Transpiration rates will fall to zero as nonpolar compounds do not have the properties necessary for adhesion and cohesion. Transpiration rates will increase as nonpolar compounds undergo adhesion and cohesion with wood fibers more readily than water. The rate of transpiration will be slightly lower with the nonpolar substance as the plant will not have evolved with the nonpolar…arrow_forwardExplain the transportation in plants.arrow_forwardWhat is the main source of carbon for living things?
