How do you appreciates role of energy conversion occurring naturally in maintaining ecological balance of nature.

Answer :

We see various energy conversions in nature, for example

i) snow deposited at altitudes melts and the water so formed flows down to seas. In the process, its potential energy converted into kinetic energy. We convert the kinetic energy of water to electrical energy in hydroelectric power plants.

ii) Dead plans buried deep below the earth’s surface for millions of years get converted to fuels like petroleum and coal, which have chemical energy stored in them.

iii) The food we eat comes from plant sources or animal sources which in turn take plant parts as their food.

iv) When we eat food, several chemical processes take place and the chemical energy stored in food gets converted into various forms needed by the body. For example when we walk, run, exercise etc., the energy from food is used for kinetic energy.
