How do bivalves feed?

Answers

Bivalves feed by filtering water through their gills and extracting food particles. They use specialized structures called cilia to create currents that bring in water. The food particles, such as plankton and detritus, are trapped by the gills and moved to the mouth using cilia. The bivalve then processes and digests the food before expelling waste materials.
