PhotoRespModel

Carbon Cycle/Oxygen Cycle: Mater cycles and energy flows. We have learned that organic compounds contain carbon. Plants make their own food and this food a carbohydrate/simple sugar/glucose. Food refers to organic compounds that organisms can use for growth and metabolism.

How might we make a paper model showing how matter cycles and energy flows in photosynthesis and cellular respiration.

Model Pieces Two organisms are needed and at least one must be able to photosynthesize You need two organelles. Photosynthesis and cellular respiration will take place in these. Label each organelle with its name and process. (H) Hydrogen, (C) Carbon, and two (O) Oxygen pieces to cycle. Water, carbon dioxide, and carbohydrate pieces to put (H), (C), and (O) pieces on.
