Answer 1

Advantages: *Sun is the ultimate source of power or energy. *Without sun, no life can exist on the planet earth as the autotrophs would be unable to synthesize food. So the heterotrophs, also would'nt survive. *The sun's gravity controls the planets' rotation,revolution and precession. *Plays an imp. role in maintaining climatic order in Earth.(winds,rainfall,temperature,humidity etc.) DISADVANTAGES: *It emits harmful UV rays. As the earth's ozone layer is depleting due to the accumulation of CFCs, these harmful rays penetrate the Earth's atmosphere and seriously affect our skin causing "skin cancer"! *Excessive amount of heat weakens our body which can function beneficially only at an optimum temperature.
