I need help with the questions please!! This is about cellular respiration and photosynthesis.

This is 20 points.

Answer

1. Plants

2. Plants

3. Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.

4. Without photosynthesis there would be no supply of oxygen and slowly the oxygen would get used up by oxidation such as rust formation. Furthermore, by removing plants, all of the many many animals that depend on plants would get very very hungry and gradually die.

5. Plants and ecosystems use the sugar both as an energy source and as the basic building block for growth. When the concentration of carbon dioxide in the air outside a plant leaf goes up, it can be taken up faster, super-charging the rate of photosynthesis.

6. At least half of Earth's oxygen comes from the ocean.

7. Plants, Bacteria, Algae.

8. Protists, Animals, Fungi.
