Ecological Tolerance 2.4

Ecological range of tolerance importance

-Range of conditions like temperature, salinity, PH sunlight

-species and organisms have ranges of tolerance

How do genetics play a role in ecological tolerance & examples

Tells you what the range of their tolerance is based off of genetics

Ex: some salmon have adapted to provide range of tolerance due to genetics

the 3 different zones

Optimal range: range where organisms survive, grow, reproduce

Zone of physiological stress: range where organisms survive but experience some stress like infertility, lack of growth, and decrease in activity

Zone of intolerance: range where organisms die like thermal shocks, suffocation, lacking (food, water, oxygen)
