Calculating the Rate of Filtration of a Natural Sponge
Chapter 21: Sponges and Cnidarians
Sponges are well adapted to their stationary existence. They have evolved structures that allow water to be pumped through their bodies. The flowing water allows the sponge to obtain food, respire, circulate materials, and excrete wastes. In order to survive, the water-pumping ability of sponges must be great. You can calculate how long it takes a sponge to filter water if you…
Try This
- Assume that you have a natural sponge that can pump 24 L of water per day. You are keeping this sponge in a 48 L aquarium.
- Calculate the flow of water in liters per hour through the sponge.
Analyze Your Results
How long would it take this sponge to filter all 48 L of water in the aquarium?
