Carbon and Nitrogen Cycles
8th Grade•45 minutes
Learning Objective
I can describe how carbon and nitrogen move through the environment.
Key Concepts
Carbon and nitrogen are two major elements that compost supplies plants with, and both are very important for life.
Carbon cycles through reservoirs such as the ocean, rocks, fossil fuels, living organisms, and the atmosphere.
Nitrogen is fixed by bacteria into forms like ammonia and ammonium, which plants can then use.
