The residual air is the air that remains in the lungs after the most forceful expiration. The residual air remains in the lungs. Hence, it has no effect on respiration efficiency in mammals. The presence of non-respiratory air sacs increases the efficiency of respiration in birds. These air sacs increase the metabolic rate in birds. In insects, circulating body fluids serve to distribute oxygen to tissues. Countercurrent oxygen flow is the flow of blood through the gills in the opposite direction as the water flowing over the gills. This facilitates efficient respiration in gills of fishes.
Thus, the correct answer is 'The residual air in the lungs slightly decreases the efficiency of respiration in mammals.'

Incorrect statement:
b) The residual air in lungs slightly decreases the efficiency of respiration in mammals.
Explanation:
Respiration is the process of exchange of gases between the organism and the environment. The efficiency of respiration depends on several factors such as the surface area available for gas exchange, the partial pressure gradient of the gases, the solubility of gases, and the mechanism of ventilation.
Efficiency of respiration in mammals:
- In mammals, respiration occurs through the lungs. The lungs are highly vascularized organs that provide a large surface area for gas exchange.
- During inhalation, air enters the lungs and oxygen diffuses from the alveoli into the blood while carbon dioxide diffuses from the blood into the alveoli.
- During exhalation, the residual air (the air that remains in the lungs after exhalation) mixes with the fresh air during the next inhalation.
- The residual air does not participate in gas exchange and slightly decreases the efficiency of respiration by diluting the fresh air.
Therefore, statement b) is incorrect as it states that the residual air in lungs slightly decreases the efficiency of respiration in mammals.

In insects circulating body fluid called hameolymph does not help in the respiratory gases circulation for the body. It only circulates the food and nutrients to the different body parts. Distribution of oxygen (respiration) takes place through small air chambers called spiracles.
