Would the number of fish in a lake, along with how large they are, and how much they move, have a greater effect on the temperature of the lake than the angle of the sun's light hitting the surface of the lake?

    $\begingroup$ fish are not warm blooded... so the heat of their bodies depends on the temperature of the water... not vice versa $\endgroup$ – farrenthorpe May 12 '17 at 22:44

    $\begingroup$ This question seems fundamentally unanswerable to me. "Number, size, and activity level of fish" and "angle of light" aren't comparable quantities. You can't determine a "greater effect" without a well-defined way of comparing the input variables. Even if you defined some formula for comparison, the answer would depend hugely on other properties of any specific lake (size, location, inflow temperature, air temperature, albedo, other biota, etc.). $\endgroup$ – Pont May 13 '17 at 9:23

    $\begingroup$ This isn't comparing apples and oranges, its more like apples and socks. That being said, I think it can be an interesting and useful thought experiment to compare two things so disparate, since both could ultimately be measured in an output of Joules added to the lake. Unfortunately, the answer is going to be the sun, by a great many orders of magnitude, so its not really worth trying to finish the thought experiment here. $\endgroup$ – kingledion May 13 '17 at 19:43
