Which of the following organism respires through the body surface

Amoeba is the organism that respires through the body surface. Amoeba is a unicellular organism that belongs to the protist kingdom. The exchange of gases (oxygen and carbon dioxide) in amoeba takes place through the process of diffusion across the cell membrane. The cell membrane of amoeba is thin, flexible and permeable to gases, which allows for the exchange of gases to take place between the environment and the cytoplasm of the cell. The other options - Man, Fish, Tridax and Hibiscus - have specialized respiratory organs like lungs or gills that are adapted for respiration.
