Energy Cycle  of Living Being

Source of energy :All  matter  locks  energy in the  from of   bonds  between component  molecules and   atoms. This  energy is the chemical  energy. All  organisms  totally depend upon  this  chemical  energy of matter for their energy requirements  since however  the matter  used by organisms is not unlimited  in nature  chemical  energy cannot be the ultimate  source of energy for organisms  The ultimate source   of energy is in fact  the light  energy of  sunrays ,Green  plants absorb  solar  energy with the help   of their chlorophyll  and lock  into c or  c h bonds . synthesize  carbohydrates  in a process  called  photosynthesis  From  carbohydrates,  the green plants also synthesize  other important  substances  needed by  all organisms. This  the energy  used  by all  organisms  is ultimately  the solar  energy which  is being  continuously  harnessed  by green  plants  regenerating  the   matter from whose breakdown all organisms  derive this  energy  in the from  chemical energy.

Animals are without chlorophyll. Hence these cannot absorb and harness solar energy. These  therefore  depend  upon  plants  for the  supply  of all  materials  these  use. Thus  green plants are producers of  the  matter  used by  organisms and  non green  plants  and animals  are consumers.
