Source of Energy Input to Biological Systems

The principal source of energy input to biological systems is light from the sun. This is because all living organisms on Earth, directly or indirectly, depend on the energy from the sun for their survival.

Photosynthesis

The process by which plants convert sunlight into chemical energy is known as photosynthesis. During photosynthesis, plants use the energy from sunlight to convert carbon dioxide and water into glucose and oxygen. Glucose is used by the plant as a source of energy, and oxygen is released into the atmosphere as a byproduct.

Food Chain

Other organisms in the food chain depend on the energy stored in plants. Herbivores eat plants, and carnivores eat herbivores. When an organism consumes another organism, it obtains the energy stored in the consumed organism's cells.

Conclusion

In conclusion, the sun is the primary source of energy for biological systems. It is the source of energy that drives photosynthesis in plants, and this energy is transferred through the food chain to other organisms. Therefore, without the sun's energy, life on Earth would not be possible.
