Solution:
The correct answer is Insects.
- All living organisms respire to get energy from food.
- The process of breakdown of food in the cell with the release of energy is called cellular respiration.
- A network of tubes called tracheae are the respiratory organs of insects.
- Tracheal tubes help insects to transport atmospheric air within the body.
- Oxygenated air rushes through spiracles into the tracheal tubes, diffuses into the body tissue, and reaches the body cell.
- Carbon dioxide from the cells moves to the tracheal tubes and moves out through spiracles.
