The answer to your question is **Primary Producer**.
* **Primary Producers** are the first trophic level in a food chain and are responsible for converting solar energy into chemical energy that can be used by other organisms. This process, called photosynthesis, requires a lot of energy from the sun.
* **Secondary Consumers** are the second trophic level in a food chain and get their energy by eating primary producers. They require less energy than primary producers because they are not converting sunlight into chemical energy.
* **Tertiary Consumers** are the third trophic level in a food chain and get their energy by eating secondary consumers. They require even less energy than secondary consumers because they are not converting sunlight into chemical energy and are only one step removed from the primary producers.
The amount of energy available at each trophic level decreases as you move up the food chain. This is because some of the energy is lost as heat during the transfer of energy from one organism to the next. As a result, the primary producers require the most energy, followed by the secondary consumers, and then the tertiary consumers.
