Answer
The process of taking in of air rich in oxygen into the body is called 'inhalation'. During inhalation, ribs move up and outwards and diaphragm moves down. This movement increases space in our chest cavity and air rushes into the lungs. Exhalation is the process of giving out of air giving out of air rich in carbon dioxide is known as 'exhalation'. During exhalation, ribs move down and inwards while, diaphragm moves up to its former position. This movement reduces the size of our chest cavity and air is pushed out.

Ananya took four test tubes and filled three- fourth of each test tube with water. She labelled them A, B, C, and D (Fig). In test tube A, she kept a snail; in test tube B, she kept a water plant; in test tube C, she kept both a snail and a plant. In test tube D, she kept only water. Ananya added a carbon dioxide indicator to all the test tubes. She recorded the initial colour of water and observed if there are any colour changes in the test tubes after 2-3 hours. What do you think she wants to find out? How will she know if she is correct?
