In an ecosystem, the ultimate source of energy is the Sun. Here's a step-by-step explanation:

1. The Sun emits light and heat, which is a form of energy known as solar energy.

2. This energy is absorbed by plants through a process called photosynthesis. During photosynthesis, plants convert solar energy into chemical energy, which is stored in the bonds of glucose and other molecules.

3. When animals eat plants, they consume the chemical energy stored in the plants. This energy is then used for various bodily functions such as growth, reproduction, and movement.

4. When these animals are eaten by other animals, the energy is transferred again. This continues up the food chain.

5. Each time energy is transferred, some of it is lost as heat. This is why there are fewer organisms at higher levels of the food chain - there is less energy available.

6. Eventually, all energy returns to the environment as heat, and the cycle begins again with the Sun's energy.

So, in an ecosystem, the Sun is the ultimate source of energy because it starts the whole process.
