Question

name: ____________ date: __________ period: ____________ objective: i can explain what homeostasis is, give an example of negative feedback and explain how the respiratory system maintains homeostasis. do now: why might a lizard move repeatedly between a sunny rock and the shade on a warm day?

Explanation:

Lizards are ectothermic, meaning they rely on external heat sources to regulate their body - temperature. Moving between sun and shade helps them maintain an optimal body temperature for physiological processes. In the sun, they warm up, and in the shade, they cool down to avoid over - heating.

Answer:

A lizard moves repeatedly between a sunny rock and the shade on a warm day to regulate its body temperature. As an ectotherm, it needs to balance heat gain and loss to maintain an optimal internal temperature for proper physiological functioning.
