It is known as an emergency brake. Pulling the chain releases air pressure that hold the brakes off - so they immediately go on.

How potential and kinetic energy have been used by the planet and living organisms?

Potential energy and Kinetic energy are used by the planet by our orbit. Earth has Gravitational potential energy and so do the other planets. When a bigger object with a gravitational field comes close to a planet or rock it is pulled into the field. The planet keeps wanting to go straight, but the field keeps it in orbit. Therefore the planet is always using potential and kinetic energy to stay in orbit. EDIT: Potential is the energy inside matter when it is not moving, and kinetic is inside when it is moving. For example; if a boulder is sitting on a cliff, it is potential. Then it falls and goes down. It is moving, so it is not kinetic. Then it stops moving, and it is potential again. So the Earth is moving, using the kinetic energy. Some of the life forms(like a person sitting doing nothing) on Earth are potential. The energy flow through living organisms starts with sunlight and photosynthesis, then travels through the food chain in bite sized chunks. Primary producers, primary consumers, secondary consumers, and decomposers are all part of the food chain.
