- Temperatures are very close to the mean.
- Stable and average temperatures, posing little adaptive challenge.

Consider two habitats: Habitat A has a temperature range of 10-25°C, and Habitat B has a range of 5-30°C. What can be inferred about the thermal environment of organisms in Habitat B compared to those in Habitat A?
- Habitat B organisms encounter a wider range of temperatures. (correct)
- Habitat B organisms experience a narrower range of temperatures.
- Both ranges are within the same standard deviation
- Habitat A is more likely to require cold-adaptation.
