Invertebrate

Real World Example

Imagine trying to build a tower of blocks without a solid foundation; it keeps collapsing no matter how carefully you stack the blocks. This is similar to how an invertebrate functions without a backbone—lacking that central support structure. Just as the tower relies on the stability of its base to stand tall, vertebrates rely on their backbone for structure and support, while invertebrates have other ways to maintain their form and carry out their functions.
