Science Unit - Earth Cycles and Systems
by Steven D. Wall, M.A.
This unit explores the importance of the cycling of water, carbon, and nitrogen on Earth and how those cycles affect ecosystems and the organisms that live in them.
You will also explore the relationships among organisms in an ecosystem by examining food chains and food webs.
Finally, you will apply what you have learned to real-life applications by researching farming practices and experimenting to see how fertilizer use affects plant growth.
