Aerobic and anaerobic respiration each have advantages under specific conditions. Aerobic respiration produces far more ATP, but risks exposure to oxygen toxicity. Anaerobic respiration is less energy-efficient, but allows survival in habitats which lack oxygen.
Within the human body, both aerobic and anaerobic respiration are important.

 Answer:
Answer is A. Vicariance does not require organisms to disperse.
Explanation:
Vicariance occurs when there is a sudden occurrence barrier , such as geographical area barrier that cause the isolation of species of organisms.
Dispersal involves the movement of the organism while vicariance is the change in environment due to sudden occurrence in the area.
In this case, vicariance  does not involve movement of organisms while dispersal involves movement of organisms.
