Answer: The third and fifth statements are true. Oxygen released from photosynthesis is breathed in by animals to break down glucose, and the carbon dioxide released by animals is used to build glucose in photosynthesis.
Explanation: Oxygen and glucose are the reactants for cellular respiration in animals. Oxygen is breathed in through the air, which is produced by plants. When the process of cellular respiration is complete, animals breathe out carbon dioxide as a product, which plants need to perform photosynthesis. Plants perform photosynthesis and send oxygen into the environment. The reactants of photosynthesis are the products of cellular respiration in animals, and vice versa, but the reactants and products are not the same.
