What does photosynthesis do? (5) a. Photosynthesis is the process in which energy is released into an ecosystem. 3. Write the chemical formula for photosynthesis and explain it clearly. (10) CO2 + H20 Light C6 H12 O6+O2 a. Carbon dioxide and water bond with light to produce glucose, oxygen, and releases energy for life functions. 5. Write the chemical formula for cellular respiration and explain it clearly. (10) C6 H12 O6+O2 CO2 + H20 a. Glucose and oxygen bond to yield carbon dioxide, water, and energy for life functions. 6. Describe each step of the scientific method. (10)
