Feel the end of your nose. We can bend the nose easily. There is a cartilage in the end of our nose. It is the presence of cartilage which gives support and shape to our nose. From the above discussion we endide that cartilage gives support and shape to organs like ears and nose.

Camilage is also found on the ends of bones where they meet one another at a joint. Cartilage is smooth. The layer of smooth cartilage reduces friction and allows the ends of bones to move easily over each ther without damaging them. Thus, cartilage is found in the joints of our body.

Discs of cartilage are present between the various small bones (vertebrae) of the backbone. The presence Milage discs between vertebrae makes the backbone flexible, so that it can bend. The cartilage discs aborb the shocks when we run, jump, or do other such activities.

Since life on earth depends on carbon- based molecules most of these food sources are also carbon-based Depending on the complexity of these carbon sources, different organisms can then use different kinds of nutritional processes The outside sourc
