Cold-Blooded Animals: How Ectotherms Regulate Body Temperature #2996117 (License: Personal Use)

This educational illustration depicts a green frog in two contrasting environments: a snowy winter scene with bare trees and a low thermometer reading, and a vibrant summer landscape with blooming flowers, lush foliage, and a high thermometer. The image visually explains that cold-blooded (ectothermic) animals do not generate internal heat; instead, their body temperature fluctuates with ambient conditions. The handwritten caption reinforces this core biological principle.

Used in K-12 science curricula, biology textbooks, or educational websites explaining animal physiology and thermoregulation; targets learners seeking foundational knowledge about ectothermy versus endothermy.
