Less energy is available on every level. This is due to the fact that each organism uses up part of the energy for its own maintenance. Only a small fraction gets stored in the parts that are eaten by the next level - such as roots, fruits, or meat.

Food chain
There is a piece of filament in every light bulb, which has so much friction that when the electric current passes through it, heat energy is produced. This heat energy is then converted to light energy.
Other than what??? Refraction will happen any time light passes from one material to another.
Sound is a vibration. It passes on energy from one molecule to another.
I DO NOT KNIOW
No. Refraction does. A single wave doesn't encounter interference until there's another wave present.
energy is independent of medium it passes through?
A "food chain" or a "food web" should suffice.
Passage of energy from one organism to another in a particular sequence is the food chain. The water cycle is a biogeochemical cycle consisting of an alternation of evaporation and condensation.
In an ecosystem energy passes from one feeding level to another. Producers are plants that occupy the first level in the ecosystem. They are the only organisms that can convert the sun's energy into chemical energy through photosynthesis. When plants are consumed, energy is passed on the herbivores and then carnivores. Without producers in the food chain there would be no energy produced for other consumers of the food chain, which is vital to daily life.
