Early scientists classified sponges as plants because of their stationary nature and lack of obvious sensory organs. It was not until the 18th century that sponges were recognized as animals due to their ability to move, feed, and reproduce like other animals.
Scientists classify sponges based on their body structure, specifically the presence of pores through which water flows for feeding and gas exchange. Additionally, they consider the type of skeleton sponges have, whether it's made of calcium carbonate, silica, or spongin fibers.
Sponges belong to a group of animals that scientists classify as Po-lifer and are among the simplest of animals, lacking tissue and organs. They filter water through the various chambers within it, absorbing nutrients
Scientist classify plants as producers due their ability to make their own food. They are in the autotrophic level of the nutrient cycle.
Because they are living animals, like starfish and sea cucumbers.
