Ascientist is monitoring the water quality of two lakes. one lake contains a high level of intolerant fish. the other lake contains a low level of intolerant fish. which lake most likely has better water quality? why?
now

The lake with high level of intolerant fish has a high quality of water.

Intolerant fishes can be described as the fishes which need a special environmental conditions for their survival like high quality of nutrients, high oxygen content in water and temperature etc.

While tolerant fishes can live in a wide range of environments like low quality of water.

So when in a lake there is high amount of intolerant fishes it means it contains high amount of quality water.

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.
