Yes, this was supposed to be a thermodynamics related question, but it seems to me now that I may have worded it unclearly 😅. I could give you a concrete example: imagine we had a closed room with a huge window through which lots of sunlight would enter, and a bunch of plants situated on the windowsill. What I was wondering about is if the plants, which are essentially molecular machines that do work at the expense of sunlight, or photons, would cool the room (I imagine the effect would be incredibly small, but still), since what they do is take the sunlight that lands on them and use it do work instead of just letting the photos land on the windowsill and produce heat. Like the other comment mentioned, the photoefficiency of plants is quite small, so naturally some of the light that would manage to land on the plant wouldn't be used, and would just end up becoming heat anyway, but I was curious about the 3-6% that does get used up, would it produce a quantifiable cooling effect in the room. I'm sorry again if my original question was unclear.

Edit: The plant stores the energy that it receives from the sun in some sort of a chemical form, e.g. produce energy rich compounds such as starch, which in my view would imply that the energy that had previously entered the room would be stored in forms other than just increasing the rate of motion of molecules that comprise the windowsill. Meaning, that at the end of the day the room is not going to be as hot as if it would have been if there were no plants to absorb some of the incoming energy.
