Sun as a ultimate source of energy

food molecules broken down during respiration to obtain energy are produced directly or indirectly during photosynthesis a process energized by the radiant energy of the sun.the green plant traps part of the radiant energy reaching the earth through the chlorophyll and convert this into chemicals energy stored in the food molecules

animals and fungi that can not synthesise their own food utilize the food molecules synthesis by the green plant directly by feeding on plant or indirectly by feeding on animal that feed on plant.hence. the sun is said to be the ultimate source of energy required to carry out biological activities. The amount of living organisms that can be sustain within a unit area on earth. surface depend to a very large extent on the available solar energy

The sun is also an important source of energy for running several domestic and industrial activities. energy from the sun is used for drying wet things such as clothes on the line. fresh crops like bean.rice and cocoa.a type of battery for generating electricity can also be charge by solar energy. energy obtain through burning of fuel such as gas.oil. coal and firewood use to power engine. Machine and some other equipment are actually solar energy lockup in dead organic matter
