THE CARBON CYCLE-part 1 What Is Carbon? An element (a type of atom) On Earth, Almost Everything Contains Carbon! Rocks (land) Oceans (water) Atmosphere (air) Plants Animals Carbon Cycle The same carbon atoms are used over and over on earth. They cycle between the earth and the atmosphere. How does Carbon get to Earth? Plants use carbon in the form of Carbon Dioxide (CO2)… Plants pull carbon dioxide from the atmosphere and use it to make food. The carbon becomes part of the plant (stored food). How does Carbon get to Earth? This is called… photosynthesis. Equation: Carbon Dioxide + Water Food + Oxygen or CO2 + H20Glucose + O2 Where does this happen in a plant? In the cells of leaves Plants make food (glucose) through photosynthesis. Glucose (sugar) provides energy for cell processes. Where does this happen in a plant? In microscopic structures called “chloroplasts.” Where does the energy come from to make glucose? The SUN!!! Photosynthesis: Review: 1. Where does carbon move from and to? 2. What is the equation? 3. What kind of organism can do this? 4. Where does it happen in the cells of these organisms?
