Release of Energy – Detailed Explanation

Introduction Release of Energy   Food web organisms transmit energy from producers to consumers. Organisms require energy to complete complicated activities. The great majority of energy in food webs comes from the Sun and is turned (processed) into chemical energy via the photosynthesis process in plants. When molecules are broken down during respiration in plants, a […]
