list four different ways in which Oragnanisms carry out exchange of gasses for respiration, with one example of each
Answers
Answer:
pulmonary respiration.e.g human being..branchial respiration through gills.e.g fish..cutaneous respiration through skin..e.g earthworm
Answer:
1. Through Plasma Membrane
In unicellular animals, such as amoeba, exchange of gases takes place through cell surface. They absorb oxygen from the surrounding air or water and give out carbon dioxide through plasma membrane by diffusion.

2. Through Body Wall or Skin
Tapeworms, earthworms, and leeches use their skin for the exchange of gases. The skin of Earthworms is very thin and moistened. Many blood cells are spread on this skin. These blood cells are known as capillaries. The exchange of gases occurs at capillaries. They die of suffocation if their skin is dried up.
respiration in animals
Amphibians such as frogs use more than one organ of respiration during their life. They breathe through gills while they are tadpoles. Mature frogs breathe mainly with lungs and also exchange gas with the environment through skin.

3. Through Tracheal System
In insects like cockroaches, grasshopper, transportation of gas or gaseous exchange take place by a special type of fine tubes is called tracheae.
respiration in animals
Air containing oxygen enters through spiracles into the tracheal tubes. It then diffuses into the body tissue and reaches every cell in the body. Carbon dioxide released from the cells goes into the tracheal tubes and comes out through spiracles.
4. Through Gills
A majority of aquatic animals like fish and prawns breathe through special organs called gills. Gilla are projections of the skin that help in using oxygen dissolved in water. Gills contain blood vessels which help in exchange of gases.
