A comprehensive introduction to the carbon cycle. The cycle of atoms between living and non-living things is known as a biogeochemical cycle. The most common of these are the carbon and nitrogen cycles.

Useful introduction to the carbon cycle with a diagram and a discussion of the effects of carbon dioxide on the greenhouse effect and global warming.

Understand the role that the carbon cycle plays in the ecosystem.

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...

The carbon cycle is one of the most important cycles. It is the biogeochemical cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the Earth. This cycle is important because it...

This teacher website provides a comprehensive lesson unit on the structure of Earth's atmosphere and how it sustains and impacts life on Earth and its ecosystems. Includes labeled diagrams, student worksheets, a slideshow, flashcards,...

Through discussion and hands-on experimentation, students learn about the geological (ancient) carbon cycle. They investigate the role of dinosaurs in the carbon cycle and the eventual storage of carbon in the form of chalk. Students...

In this activity, students make Moebius strips and use them to demonstrate the interconnectedness of an environment. They will explore the natural cycles (water, oxygen/carbon dioxide, carbon, nitrogen) within the environment.

At this site from NASA you can understand how phytoplankton help the carbon dioxide levels between the oceans and the air stay in balance.
