I say this becasue "</span><span>Some of the sounds dolphins make are outside the range of human hearing."

Answer is: adenosine triphosphate.
ATP is made of three components: the triphosphate (P), the sugar ribose and a nitrogenous base (adenine).
ATP is short for adenosine triphosphate
Adenosine triphosphate converts to either the adenosine diphosphate (ADP) or adenosine monophosphate (AMP), in this process energy is released.
