Animals like lizards take advantage of this by basking and burrowing. C. Advantages and Disadvantages 1. Less energy is needed to survive. Entirely dependent on environment. If the environment isn't warm, the animal can't heat up.
Animals are vulnerable during warm up period.
Animals spend a lot of time at temperatures other than their preferred temperature. In some environments, thermal heterogeneity is difficult to find. D. Adaptations Certain enzymes, like muscle enzymes, work over a broad temperature range. This enables the animal to be active at temperatures lower than the preferred body temperature.
