Directions: construct a diagram that includes all the relevant processes between the ecological cycles (water carbon and nitrogen). Your project should show imagination and creativity. All aspects of each process should be shown and labeled:
Carbon:
• Photosynthesis
• Cellular respiration
• Decomposition
• Burning of Fossil Fuels

(Accurate labeling and arrows showing movement throughout the ecosystem)

photosynthesis makes the glucose that is used in cellular respiration to make atp. the glucose is then turned back into carbon dioxide, which is used in photosynthesis. while water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.

blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium of the heart. as the ventricle contracts, blood leaves the heart through the pulmonic valve, into the pulmonary artery and to the lungs where it is oxygenated.
