IB Biology HL B4.1.4 Range of tolerance of limiting factor
Practise reading tolerance graphs, calculating ranges, and predicting how limiting factors such as temperature, pH, light, or water affect species distribution.
How this is tested
- interpret graphs to compare optimum and maximum tolerance values between species
- calculate tolerance ranges from data and use units such as degrees Celsius correctly
- predict distribution or timing changes when a limiting factor moves beyond tolerance limits
