Yeast : Alcohol


Yeast get energy through anaerobic respiration. They are known as anaerobes. In the absence of oxygen, glucose breaks down into alcohol and carbon dioxide.


Diaphragm : Chest cavity


A large, muscular sheet called diaphragm forms diaphragm the floor of the chest cavity. The movement of the diaphragm and the rib cage are involved in the breathing.


Skin : Earthworm


The skin of earthworm is moist and slimy through which they respire.


Leaves : Stomata


The leaves of the plants have tiny pores called stomata for exchange of oxygen and carbon dioxide.


Fish : Gills


Fishes respire through gills. Gills are projections of the skin.


Frog : Lungs and skin


Frogs have pair of lungs for respiration, they also respire through their skin which is moist and slippery.
