The Carbon Cycle
- Study the diagram
- read the notes after it
- attempt the carbon Cycle quiz
Carbon atoms are found in all food molecules. They form the framework. Food molecules include starches sugars fats and proteins
Carbon starts out as carbon dioxide in the atmosphere. Plants trap it as food molecules during the process of photosynthesis. Carbon is first stored in producers.
Carbon is passed from producers to consumers as plants are eaten
At each stage as living things breathe and respire to release oxygen carbon is returned to the atmosphere as carbon dioxide. (you respire, you breathe air in and breathe out carbon dioxide)
Some of the carbon inside plants gets trapped in wood coal and oil.. When we burn fuels to release energy the carbon is returned to the atmosphere as carbon dioxide.
