Range Of Tolerance

Imagine trying to find the perfect water temperature for a comfortable shower. Just like how you have a preferred range of water temperature that's not too hot or too cold, species have a range of environmental conditions they can tolerate to survive. The too-hot shower makes you uncomfortable just as extreme temperatures can stress a species, while the perfect shower temperature is like the optimum conditions where species thrive. So, just as you have a minimum, maximum, and ideal shower temperature, species have specific environmental limits that define where they can live comfortably.
