Chapter 16: Problem 3

List 3 ways in which animals keep their body temperature constant when the weather is hot

Short Answer

Expert verified

Animals keep their body temperature constant using methods such as evaporative cooling (panting or sweating), behavioral adaptations (resting in the shade), and physical adaptations (large ears for heat dissipation).

Step by step solution

- Understanding Thermoregulation

It's crucial to know the term 'thermoregulation'. Thermoregulation is a process that allows your body to maintain its core internal temperature. All thermoregulation mechanisms are designed to return your body to homeostasis.

- Identifying Animal Adaptations for Heat

Set out to identify three mechanisms or adaptations animals utilize to keep their body temperature constant when the weather is hot. There are indeed multiple ways, but for this exercise, we only need to list three.

- Description of the Adaptations

Start by describing the following three adaptations: 1) Evaporative Cooling: Animals resort to activities that allow evaporation. These include panting or sweating, which permit the animal to dissipate heat through water evaporation. 2) Behavioral Adaptations: Animals also opt for behavioral strategies like resting in the shade during the hottest parts of the day to reduce exposure to heat. 3) Physical Adaptations: Certain animals have physical attributes like large ears in elephants that are filled with blood vessels, allowing heat to escape quickly.
