Food provides animals with the energy and nutrients they need to survive. Energy is used for movement, growth, and reproduction. Nutrients are used for building and repairing tissues, producing enzymes and hormones, and regulating bodily processes. Without food, animals would quickly become weak and die.
To grow and develop
Young animals need food to grow and develop. They need more food than adult animals, because their bodies are growing rapidly. Food provides them with the nutrients they need to build new cells and tissues.
To reproduce
Animals need food to reproduce. Reproduction requires a lot of energy, and food provides the energy that animals need to produce eggs or sperm and to care for their young.
To stay healthy
Food helps animals stay healthy. It provides them with the nutrients they need to fight off infection and disease. Animals that are well-nourished are less likely to get sick.
To survive in the wild
Animals that live in the wild need food to survive. They must find food in order to compete with other animals and predators. Food also helps them store energy for times when food is scarce.
