Ecology of Mollusks Mollusks filter algae by eating detritus, which cleans their environment. Mollusks are a source of food for organisms and humans. Bacteria produce food molecules that are essential to mollusks. Checking bivalves can keep scientists aware of dangers in open waters. They monitor water quality and health problems that health officials aren’t aware of.
Comparing Groups of Mollusks `There are three different groups of mollusks inside the Mollusca Phylum, they include gastropods, bivalves, and cephalopods. Cephalopods are shell-less unlike Bivalves that have two shells and Gastropods who have 0-1 shell(s). Gastropods use their shells to protect themselves from predators but bivalves flap their shells flee from predators. Bivalves use long, muscular extensions of tissues that surrounds their mouth to get food les from the sediment around them. Cephalopods,on the other, hand use tentacles with sucking disks to capture and bring in their prey.
