Detailed explanation-1: -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-2: -Energy enters an ecosystem when producers carry out photosynthesis, capturing energy from the sun and storing it as chemical potential energy. During this process, matter from the environment is taken in and rearranged into organic molecules (sugars).
Detailed explanation-3: -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.
Detailed explanation-4: -Unlike the one-way flow of energy, matter is recycled within and between ecosystems. Elements pass from one organism to another and among parts of the biosphere through closed loops called biogeochemical cycles, which are powered by the flow of energy.
