Unicellular organisms evolved first; and from them evolved the multicellular organisms. But that leads onto another question as to why multicellular organisms evolved.

What are three ways that sponges represent the transition from unicellular to multicellular?

Sponges exhibit characteristics of both unicellular and multicellular organisms, demonstrating the transition between the two. First, they are composed of specialized cells that perform distinct functions, such as choanocytes for feeding and pinacocytes for protection, while still lacking true tissue organization. Second, sponges can regenerate and reassemble from individual cells, highlighting their cellular cooperation. Lastly, they possess a simple body plan with a porous structure that allows for the efficient flow of water, facilitating nutrient and gas exchange, akin to how multicellular organisms optimize their internal processes.
