Question

multiple choice question
what type of organism must rely on behaviors and the environment, rather than its own metabolism, to adjust its temperature?
o ectotherm
o endotherm
o autotroph
o heterotroph

Explanation:

Ectotherms, like reptiles, use external heat sources (e.g., sun - basking) and behaviors (e.g., moving to shade) to regulate body temperature. Endotherms (e.g., mammals) generate heat via metabolism. Autotrophs produce their own food (e.g., plants via photosynthesis). Heterotrophs consume other organisms for energy. The question asks about relying on environment/behavior (not metabolism) for temperature - adjustment, which fits ectotherms.

Answer:

ectotherm
