Solution

(a) Organism B is undergoing aerobic respiration.

(b) Organism A is undergoing anaerobic respiration.

(c) In anaerobic respiration, glucose breaks down to form alcohol and carbon dioxide with the release of small amount of energy. Hence, organism A can convert glucose into alcohol.

(d) Yeast behaves like organism A.

(e) Humans and dogs behave like organism B.
