What type of adaptations are particularly important in extreme environments?

Behavioral adaptations
Morphological adaptations
Physiological adaptations
Ecological adaptations

The correct answer is: Physiological adaptations

In extreme environments, organisms must have physiological adaptations in order to survive. This can include special mechanisms for regulating body temperature, or being able to withstand extreme temperatures. Behavioral adaptations may also be important, but they are not specifically targeted towards adapting to extreme environments. Morphological adaptations refer to physical characteristics, which may or may not be relevant in extreme environments. Ecological adaptations are specific to interactions between organisms and their environment, and may not be related to survival in extreme conditions. Therefore, physiological adaptations are the most important type of adaptation in extreme environments.
