Explain Activity 6.6 NCERT Class 10 Science Life Processes

You can learn object, material required, procedure, observation, and conclusion of activity 6.6 NCERT class 10 science life processes.

Object – To observe the rate of respiration of aquatic animals

Material required - Water container with fishes

Procedure – Terrestrial animals can breathe the oxygen present in the atmosphere but aquatic animals need to use the oxygen dissolved in water.

The amount of oxygen dissolved in the water is fairly low as compared to the amount of oxygen in the air.

The process of gaseous exchange is almost the same in all animals but the respiratory organs are different. In fish respiratory surface is the surface of their gills. Due to the unique structural features, gills have a large surface area. Gills are thin and have a good blood supply.

Fish open its mouth and gills so frequently to meet their demand for oxygen.

Observation – The rate of respiration in aquatic animals is higher than it is in terrestrial animals.
