Detailed explanation-1: -Inside the cells of plants, algae, and photosynthetic bacteria, chlorophyll, and enzymes use the light energy to rearrange the atoms of the reactants to form the products, molecules of glucose and oxygen gas.
Detailed explanation-2: -Answer and Explanation: The four substances recycled during photosynthesis and respiration are carbon dioxide, water, oxygen and glucose. Respiration uses the products of photosynthesis, oxygen and glucose to form ATP energy, carbon dioxide and water.
Detailed explanation-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.
Detailed explanation-4: -Unlike energy, matter is recycled in ecosystems. Decomposers release nutrients when they break down dead organisms. nutrients are taken up by plants through their roots. nutrients pass to primary consumers when they eat the plants.
