Smaller animals, often referred to as "small mammals," include species like mice, hamsters, and rabbits. These creatures typically weigh less than a few pounds and can be found in various habitats, from forests to urban areas. Their size allows them to hide from predators and adapt to different environments. Many smaller animals play essential roles in their ecosystems. For example, mice are important seed dispersers, while rabbits help maintain plant growth by grazing. Additionally, they serve as food for larger predators, contributing to the balance of their habitats.
