mosquito larvae can tolerate extremely low dissolved oxygen concentrations, yet cannot survive at temperatures above 25 degrees celcius. how might you aaccoundt for dissolved oxygen concentrations of such a low value at a temperature of 25 degree celcius?

I don't understand how this can be because as the temperature of an area increases, then the concentration of dissolved oxygen increaes.

Nope, dissolved oxygen is highest at low temps. Now you know in the summer fish are at the bottom of rivers and streams.

yes, that is what i meant but i don't understand why the dissolved oxygen concentration would be so low at such a low temperature?
