|
|
They have a larger SA:V ratio and need to release more heat energy to stay warm.
|
|
|
They need more energy because they move around more
|
|
|
They have a higher body temperature so they need to release more heat energy
|
|
|
They eat continuously and therefore have more glucose available for respiration

Detailed explanation-1: -Since animals exchange heat with their environment across their body surfaces, small animals will tend to lose heat to a cooler environment faster than large animals.
Detailed explanation-2: -The surface-area-to-volume ratio is also called the surface-to-volume ratio. Animals generate heat internally in proportion to their volume. The larger the volume of the animal the more heat it can produce. Animals lose heat externally in proportion to their surface area.
Detailed explanation-3: -Both are endothermic, however a mouse can lose heat through its skin much faster than an elephant because a mouse has a higher surface area to volume ratio than an elephant.
Detailed explanation-4: -Answer. The smaller the animal, the larger is the surface area to volume ratio. Therefore, a small animal like a shrew has a greater potential for losing heat from its body because of its relatively large surface area.
