The carbon cycle is important because all living things are made of carbon in one way or another. The carbon cycle is how carbon is exchanged throughout the earth: between the atmosphere, oceans, ecosystem and geosphere.... More »

The Carbon Cycle Game is a game that allows students between grades 6 and 12 to learn about the role of carbon in climate change. The game teaches that carbon cycles through four spheres and that the amount of carbon cha... More » Science Earth Science

The simple carbon cycle can be broken down into three main processes: photosynthesis, respiration and combustion. These processes combine to recycle carbon in the atmosphere and synthesize new carbon sources. More »

The ocean is important to life on Earth because of the role it plays in both the hydrologic cycle and the carbon cycle. The hydrologic cycle, also known as the water cycle or H2O cycle, refers to the relationship that ex... More »

Decomposers help reclaim carbon from dead organisms and put it back into the carbon cycle so living organisms can use it. Decomposers break down dead plants, animals and waste products. This process releases carbon dioxi... More »

An ecosystem is a location where living things such as plants and animals live with each other in a community among non-living things such as rocks and water. An ecosystem is part of a larger area known as a biome. Examp... More »

Matter is recycled in an ecosystem through various cyclical processes, such as the oxygen cycle, carbon cycle, water cycle and nitrogen cycle. The oxygen cycle, for example, is driven by photosynthesis and enables the ex... More »
