How does energy transfer work in natural systems?

Energy transfer in natural systems occurs through processes such as photosynthesis, respiration, and food chains. In photosynthesis, plants convert sunlight into chemical energy, which is then passed on to animals that consume the plants. Through respiration, organisms release stored energy from food to fuel their activities. In food chains, energy is transferred from one organism to another as they consume each other. Overall, energy transfer in natural systems is essential for sustaining life and maintaining ecological balance.
