carbon cycle- the process by which carbon moves from inorganic to organic compounds and back.
greenhouse effect- a property that keeps the average temp. on Earth some 10 degrees Celsius warmer than it would be otherwise.
The carbon cycle is a process that occurs on Earth that the depend on the metabolism of tiny chloroplasts and mitochondria. A key element of the carbon cycle is carbon dioxide. Plants use carbon dioxide to make sugars, and organisms, consuming plants, give off carbon dioxide as waste. Carbon dioxide in the atmosphere traps heat from the sun that would have escaped from Earth into space. Some heat radiating from Earth's surface towards space is trapped by carbon dioxide (along with other types of gases) in the atmosphere. This property is called the greenhouse effect, which keeps the Earth warm enough for living things.
1. An example of carbon moving from an inorganic compound to an organic compound in the carbon cycle is a Cape buffalo eating the organic compunds by eating the plants. An example of carbon moving from an organic to an inorganic compound is the release of carbon dioxide from a Cape buffalo into the air and a plant uses the carbon dioxide in photosynthesis.
2. Because the carbon dioxide in the atmosphere traps heat from escaping into space.
