Here's why:
* Specialized Organs: Animals have evolved complex organ systems. These systems are made up of different organs that work together to perform essential functions like digestion, respiration, circulation, reproduction, and more.
* Other Kingdoms: While some members of other kingdoms might have structures that resemble organs, they are not as complex or specialized as those found in animals. For example, plants have roots, stems, and leaves, but these are not considered true organs in the same way that animals have.
