Question

read the text.
most animals need to maintain a body temperature within a narrow range. endotherms, such as humans and other mammals, can regulate their temperatures internally. when the temperature of their surrounding environment changes, endotherms may shiver or sweat to keep their body temperatures within a normal range.
for ectotherms, by contrast, a change in the temperature of the surrounding environment will usually affect the animals body temperature. ectotherms often regulate their body temperatures by moving within their environments; for instance, a lizard will lie out in the sun to warm itself up.
which term matches the picture?
image of a horse
ectotherms
endotherms

The text explains that endotherms (like mammals) regulate body temperature internally, while ectotherms rely on the environment. The picture shows a horse, which is a mammal. Mammals are endotherms, so the term matching the picture is endotherms.

endotherms
