A VERY GOOD MORNING EXPERTS ...
PLEASE ANSWER THIS : Q. GIVE REASONS FOR THE FOLLOWING STATEMENTS : 1. SUN IS REGARDED AS THE ULTIMATE SOURCE OF ENERGY . 2. THE FLAME OF A CANDLE RISES UP TO A GOOD HEIGHT AFTER BURNING PLEASE ANSWER BOTH THE PARTS IN . THREAD ITSELF ... IT WILL BE A GREAT HELP ... THNX IN ADVANCE :)
Dear student,
1) Sun is the ultimate source of energy. Sun gives us heat and light. This heat maintains the temperature of the earth balanced and life is possible on earth. Plants use sunlight and prepare food during photosynthesis Herbivores organisms are dependent on plants for energy. Carnivores eat herbivores for getting energy. So energy is getting transferred. The Foodweb is created in which plants are the producer and others are consumers. So, in the end, all organisms are indirectly using the energy of the sun.
2) The flame of a candle rises up to a good height after burning because when a candle burns the flame of the candle heats the nearby air and starts to rise. As this warm air moves up cooler air and oxygen rush in at the bottom of the flame to replace it. When that cooler air is heated, it too rises up and is replaced by cooler air at the base of the flame.
Regards
