Question
How do exchange gases take place in aquatic animals?
Solution
Most of the aquatic animals like prawns, fish, tadpoles use gills as the respiratory organs. Respiration through gills is known as branchial respiration. The blood flowing in the capillaries of gills absorb oxygen and gives carbon-dioxide to the water passing over them by diffusion through thin epithelium.
