Provide your class with the opportunity to view our carbon cycle close up. Young scientists research the cycle of oxygen as it completes the tasks of photosynthesis and respiration. They explore the importance of carbon in an ecosystem...

The fours stages of the carbon-oxygen cycle are described - photosynthesis, respiration, combustion, and decomposition.

Explains what the carbon cycle is and the basic steps in the cycle.

The importance of the carbon cycle, how it works, the sources of carbon, and the steps in the carbon cycle are explained here.

Outlines the steps for the movement of carbon along the carbon cycle through photosynthesis, food chains, being dissolved into the ocean, the decomposition of organisms, fossil fuel formation, industrial use of fossil fuels, carbon...

Complete illustrated discussion of energy flow within ecosystems, including discussions of trophic levels, ecological pyramids, food chains and webs, biological magnification, and cycles.
