Answer 1

Sponges are classified as animals rather than plants primarily because **sponges do not make their own food**. Unlike plants, which are autotrophic and produce their own energy through photosynthesis, sponges are heterotrophic and obtain their nutrients by filtering food particles from the water. This characteristic, along with other features such as their multicellular structure and lack of cell walls, aligns them more closely with the animal kingdom.
