Vedclass · Answer

(A) Respiration in $Cnidarians$ (such as $Hydra$ and $Jellyfish$) occurs through the process of simple diffusion.Since these organisms have a simple body organization and are in direct contact with the surrounding water,dissolved oxygen enters their body cells,and carbon dioxide leaves the body through the general body surface via diffusion.Fishes use gills,while amphibians and reptiles primarily use lungs or skin (in some cases) but do not rely solely on simple diffusion across the entire body surface like $Cnidarians$.
