Which of the following is an essential factor in wildlife habitat alongside food?

Water is indeed an essential factor in wildlife habitat alongside food. Any habitat that supports wildlife must provide not only sustenance in the form of food but also access to water. Animals need water for hydration, reproduction, and various physiological processes. It plays a critical role in the survival of species by supporting metabolism and acting as a necessary component for healthy ecosystems. The availability of water influences the distribution and movement of wildlife, as animals tend to gravitate towards areas where water is plentiful.

While light, temperature, and elevation also influence habitats, they are not as universally critical as water, which is a direct necessity for all living organisms. Light and temperature can affect plant growth and animal behavior, but without water, many species would struggle to survive, making it a fundamental element in maintaining a healthy and functional habitat.
