2.4 Ecological Tolerance
Notes
Each species has a range of tolerance for conditions like temperature and pH. Outside the optimal range, it experiences stress; beyond its limits, it dies.
Practice
A fish lives in water from 10–25 °C, best at 18 °C. At 24 °C it is:
Near the edge.
Coral bleaching from warm water is an example of:
Too hot.
Species with a wide tolerance range tend to be:
They handle many conditions.
