Explain whether a conformer or a regulator could tolerate a wider range of conditions.

The terms conformers and regulators are alternative terms for ectotherms and endotherms, respectively. Ectotherms do not regulate their internal temperature, whereas endotherms maintain a constant temperature. The range of conditions that ectotherms can tolerate is narrower than that of endotherms. For example, you won't find any reptiles at the polar regions.
