Hi, I am slightly confused on what this essay title actually involves "how energy is transferred within and between organisms"? Does it just mean ways in which hydrolysis of ATP can be used? I just don't get what topics would come under this. please help. (a level)

thanks. I dont really understand how transport across membranes/active immunity comes under energy transfer? How is energy transferred in these processes? What does energy transfer even really mean?

you could talk about, the light dependent reaction (photosynthesis) and respiration. Transport across membranes because during active transport uses ATP and you could talk about co-transport of sodium and glucose. Also nerve impulses and movement of Neurotransmitters across the synpatic gap i guess
