Solution
It is known that exposure to carbon monoxide is harmful to animals because It reduces O2 transport.
Explanation:
CO is a poisonous gas which binds with Hb more rapidly than O2 to form carboxyhaemoglobin. CO makes the most stable combination with the Hb of blood. CO has 200 – 250 times more affinity for Hb as compared to O2. When the inhaled air contains CO gas then a person suffers from suffocation because the product cannot dissociate so decreases free oxygen.
