a.The process of breathing in insects such as grasshopper and cockroach is very slow. Insects do not breathe like human beings. Insects do not have lungs to do respiration. In insects respiration takes place through tracheae.
b.Earthworms are found in the soil. In the soil they eat dead and decaying organic matter along with soil. In return, they help in aeration of soil by digging holes in it and enhance fertility of soil. In earthworms there is no specialized organ to do respiration. So, in earthworms respiration process takes place through its moist, thin and highly vascular skin.
c.While completely submerged all of the frog's repiration takes place through the skin. The skin is composed of thin membranous tissue that is quite permeable to water and contains a large network of blood vessels. The thin membranous skin is allows the respiratory gases to readily diffuse directly down their gradients between the blood vessels and the surroundings. When the frog is out of the water, mucus glands in the skin keep the frog moist, which helps absorb dissolved oxygen from the air.
d. In aquatic animals such as fish respiration takes place through special respiratory organs called gills, however lung fish respiration takes place through lungs. Gills are present on both the sides of the head of fish.
