The energy is derived from A.sun.
Step-by-step explanation:
- The energy from sources like Fossil fuels is received from the Producers (Plants, algae) that receives the energy directly from sunlight for photosynthesis earlier long ago. This energy when the plant dies and decomposes over a long period of time and becoming a fossil fuel.
- Fossils fuels are the remaining of the organisms that lived long back ago they are the energy source for fossil fuel which are burnt in large numbers.
- Fossil fuels once burnt can never be reused again because their medium gets converted or transferred.
