The ultimate source of all energy on earth is sunlight. Here's how it works:
1. Sunlight is essential for photosynthesis, a process carried out by plants and some bacteria.
2. During photosynthesis, plants use sunlight to convert carbon dioxide and water into glucose (a type of sugar) and oxygen.
3. Glucose produced by plants serves as a form of chemical energy that is essential for all living organisms.
4. Other living organisms, such as animals, obtain energy by consuming plants or other animals that have consumed plants.
5. Therefore, sunlight plays a crucial role in providing energy for the entire ecosystem on earth.
In summary, sunlight is the primary source of energy that drives the process of photosynthesis, ultimately fueling the food chain and providing energy for all living organisms on earth.
