Predation is a biological interaction where one organism, the predator, kills and eats another organism, its prey
Explanation:
the name porifera means pore bearer in latin. a sponges body is covered by a skin, one cell thick. this skin has lots of small pores ad a few large openings. the small openings are the entrances to a complex system of channels. these collar cells pump water through the entire sponge and filter out food for the sponge cell to eat
sorry what this means¯\_(ツ)_/¯
