3. Heat-sensitive film, which captures the body temperature of organisms on film, is used to photograph the mammals and reptiles of a pet store during normal store hours where temperature is controlled and then during a heat wave where the electricity went out. This lizard blends into the background because its body stays about the same temperature as its surroundings. A human hand stays warm because a person produces and releases a large amount of metabolic heat. cooler --------> warmer Endotherm and ectotherm. Photo of a chameleon (an ectothermic lizard) being held by a human (an endotherm). The image was taken using heat- sensitive film.

during a heat wave where the electricity went out.
This lizard blends into the background because
its body stays about the same temperature as
its surroundings.
A human hand stays warm
because a person produces
and releases a large amount
of metabolic heat.

Transcribed Image Text:4. Autotrophs harvest energy directly from the environment and store it in the form of sugars and other
carbohydrate. They and all other organisms use energy stored in sugars to power various endergonic
reactions that sustain life.
