Why do different animals have different ways of locomotion?

Explanation

**Step-by-Step Solution:**

1. **Understanding Locomotion**: Locomotion refers to the way animals move from one place to another. Different animals have evolved various methods of locomotion based on their body structure and habitat.

2. **Body Structure**: The physical structure of an animal plays a crucial role in determining how it moves. For example, animals with legs, like humans and cockroaches, walk or run, while animals like earthworms have a different structure that allows them to creep.

3. **Complexity of Body Structures**: Animals have different levels of complexity in their body structures. This complexity influences their movement. For instance, earthworms have a simple body structure that enables them to move through soil, while cockroaches have more complex appendages that allow for quick movement on land.
