Answer:
Like the mollusks, lobsters use gills for breathing. The gills are featherlike structures located in a water-filled chamber under the carapace. Each gill is attached to the upper end of a walking leg. The rapid beating of the mouthparts sends cur- rents of water over the gills. Oxygen in the water diffuses into the gills, and carbon dioxide passes from the gills out to the water.
Explanation:Lobsters use gills to breathe. Their gills are blood-filled, feathery organs which extract oxygen from water. The gills can be found at the base of the lobster's legs. ... To maintain a steady supply of oxygen, the gills circulate water for lobsters the way our respiratory system circulates air to breathe.
