Detailed explanation-1: -Insects have a highly specialized type of respiratory system called the tracheal system, which consists of a network of small tubes that carries oxygen to the entire body. The tracheal system is the most direct and efficient respiratory system in active animals.

Detailed explanation-2: -Usually animals such as earthworm has a system to provide atmospheric oxygen directly to the body cells. Explanation: Earthworm has its respiratory organ as it’s lungs. In earthworm the oxygen diffuses from the body cavity to the haemocoel.

Detailed explanation-3: -Respiration is important because it produces energy that is necessary for the functioning of the body. It provides oxygen to the cells and expels toxic carbon dioxide. When oxygen reaches the cells, this oxygen breakdown glucose which is present in digested food, and releases energy.

Detailed explanation-4: -The cells in our bodies need oxygen to stay alive. Carbon dioxide is made in our bodies as cells do their jobs. The lungs and respiratory system allow oxygen in the air to be taken into the body, while also letting the body get rid of carbon dioxide in the air breathed out.
