Q: What cycle vital to plants includes a process called denitrification? Read this paragraph and choose the correct option from the provided answers: 3.4 NITROGEN: RUNNING IN CYCLES Introduction: In the previous assignment, you studied the carbon cycle. In a previous unit, you described the water cycle. Carbon and water are matter. As you learned in the first unit, matter cycles. Nitrogen is another form of matter that cycles. Like water and carbon, nitrogen is essential to life. Also, like water and carbon, its cycles affect you. Therefore it is important that you learn about the nitrogen cycle, how it affects you, and how you affect it. Assignment: There are three parts to this assignment. You must complete all three parts to receive credit for the assignment. Be sure to turn in all three parts at the same time. I will not correct partial assignments. THANKS! PART ONE: 1. Describe the nitrogen cycle. Describe how nitrogen goes from the atmosphere to a form usable to plants, how it is used and excreted by animals, and how it returns to the atmosphere. In your description be sure to explain the words: * decay * denitrification. Choices: - carbon cycle - sedimentation cycle - photosynthesis - nitrogen cycle A:
nitrogen cycle
