Mammal

Example:

Imagine you're trying to keep your house at a comfortable temperature throughout the changing seasons, ensuring it's warm in winter and cool in summer. Mammals, like this house, have an internal system that maintains a stable internal environment, regardless of the external conditions, which is known as being warm-blooded. Just as a thermostat and heating system work together to regulate your home's temperature, a mammal's body regulates its temperature and provides nourishment to its young through milk, ensuring their growth and survival, much like how you ensure the comfort and well-being of your family in your home.
