Energy is vital for living organisms is our fuel . if there is no energy formed we can t talk about life because things cells that are too little to experience things have this purpose to form energy in order for us to function.we need to see the human body in a constant dynamic because every second is breaking and forming Atp( the primary source of energy) and using that atp for everything moving thinking keeping us healthy ex transporting macromolecular substances like glucose that is lately broke down (glicolisis) and forms other molecules of AtP .And the cycle goes on.In my opinion is decisive because if there is no energy there is no life the other things could work if the the everyday light goes away the moon can still be there we can still be there but at some point we will dissapear.Energy is requiered for everything to occur it repairs builds and maintains body tissues without it the has no chance to survive .Because there will be no metabolic processes and no cycle of energy exchanges.
