Animals are living beings that encompass a vast range of species inhabiting our planet. They are characterized by their ability to move, consume food, and reproduce. From tiny insects to colossal marine mammals, animals exhibit incredible diversity in size, shape, behavior, and habitat. They can be found in virtually every ecosystem on Earth, adapting to various environmental conditions. Animals play crucial roles in maintaining ecological balance, as they serve as prey and predators, pollinators, decomposers, and even contribute to nutrient cycling. Additionally, many animals provide companionship to humans and offer support in various fields like agriculture, therapy, and research.
