1. What else do organisms need to acquire from the environment aside from nutrition? Why? 2. What gas is considered as a metabolic waste product of cellular respiration? How does it leave the organism's body? 3. Cite some structures in plants and animals that allow the gas exchange. 4. Enumerate some respiratory problems encountered by humans that alter the normal process of gas exchange.
