Which of the following is an example of how the need to maintain homeostasis can cause an organism to change its behavior? a A bear hibernates during the winter. b A tree loses its leaves in the winter. c A human shivers when exposed to cold weather. d Organisms do not change their behavior to maintain homeostasis.

A bear hibernates during the winter to conserve energy and maintain its body temperature when food is scarce. This behavior helps it survive the harsh conditions by reducing metabolic rates and utilizing fat reserves until spring returns with plenty of food options. Nature’s clever way of kicking back in a cozy nap! Humans shiver when exposed to cold weather as a response to maintain warmth and prevent hypothermia. This involuntary muscle reaction generates heat through rapid contractions, showcasing how our bodies cleverly adapt to environmental challenges—kind of like turning on a heater when the temperature drops!
