Answer:

Column I                             Column II
(a) Yeast                             (iii) Alcohol
(b) Diaphragm                    (iv) Chest cavity
(c) Skin                               (i) Earthworm
(d) Leaves                          (v) Stomata
(e) Fish                               (ii) Gills
(f) Frog                               (vi) Lungs and skin              

 

1. Yeast: Yeast is a single- celled organism which respries anaerobically. Yeast is used to produce alcohol by fermentation process by converting glucose into alcohol. 

2. Diaphragm: The diaphragm is made up of rib cage. It is present in chest cavity. It expands inside when we inhale and during exhalation it contracts.

3. Earthworm: The earthworm respires through skin. The skin of earthworm is slipery and soft. Exchange of gases takes place through the skin. 

4. Leaves: Tiny pores present on the surface of the leaves called stomata. Stomata are the beans shaped structure which is protected by the two guard cells and helps in the exchange of gases. Transpiration of water also occurs through stomata.

5. Fish: Fish respires through gills. The breathing rate of fish is faster than the terrestrial organisms because they use dissolved oxygen in the water which is less in quantity as compared to the environment. 

6. Frog: Frogs respire through lungs as well as skin. Because frog acquires terrestrial as well as aquatic habitat.
