Carbon moves from the atmosphere to plants. In the atmosphere, <em>carbon is attached to oxygen in a gas called carbon dioxide (CO2)</em>. Through the process of <u>photosynthesis, carbon dioxide is pulled from the air to produce food made from carbon for plant growth.</u>
<u>Carbon moves from plants to animals. Through food chains, the carbon that is in plants moves to the animals that eat them. Animals that eat other animals get the carbon from their food too.</u>
<u>Carbon moves from plants and animals to soils. When plants and animals die, their bodies, wood and leaves decays bringing the carbon into the ground. Some is buried and will become fossil fuels in millions and millions of years.</u>

Gas exchange is the delivery of oxygen from the lungs to the blood stream, and gets rid of carbon dioxide from the blood. It occurs in the lungs between the alveoli and a group of capillaries.
