Which of the following is NOT one of the four major requirements of animals?

The four major requirements for animals include food, shelter, water, and air, which are essential for their survival and well-being. Food provides the necessary nutrients and energy that animals need to function and reproduce. Water is crucial for hydration and various biological processes. Shelter offers protection from environmental hazards, predators, and extreme weather conditions, contributing to an animal’s overall safety and comfort.

Clothing, however, is not a requirement for animals. While some animals may have natural coverings such as fur, feathers, or scales, which serve protective and insulating purposes, they do not require clothing in the way that humans do. Clothing is a human construct used for various reasons, including fashion, protection, or social status. Thus, it does not belong to the fundamental needs that animals must have for survival. This understanding highlights the essential difference between human necessities and the basic biological requirements of animal life.
