Question
Sponges are most accurately described asa) marine predators.b) marine filter feeders.c) freshwater scavengers.d) aquatic filter feeders
Solution
Sponges are most accurately described as b) marine filter feeders.
Here's why:
-
Sponges, also known as Porifera, are simple multicellular organisms that live in marine and freshwater environments, but the majority are marine species.
-
They are not predators. Predators actively hunt and capture their prey, but sponges feed in a much different way.
-
Sponges are filter feeders. This means they draw water in through their pores, filter out the organic matter and bacteria for nourishment, and then expel the cleaned water back out. This process is passive, meaning they don't actively seek out food.
-
While there are some freshwater sponge species, the majority of sponges are found in marine (saltwater) environments. Therefore, describing them as marine filter feeders is more accurate than saying they are freshwater scavengers.
-
The term "scavenger" implies that an organism feeds on dead and decaying matter, which is not the primary method of feeding for sponges.
So, the most accurate description of sponges is "marine filter feeders."
