Answer:

Only species Y is anaerobic.

Explanation:

  • Cellular respiration refers to the process in which food substances such as glucose are broken down to yield energy in the form of ATP, water and carbon dioxide as by-products.
  • Respiration may be either anaerobic or aerobic respiration.
  • Aerobic respiration is a type of respiration that takes place in the presence of oxygen. Nutrients are broken down to yield energy, water, and carbon dioxide.
  • Anaerobic respiration occurs in the absence of oxygen to yield few molecules of ATP, alcohol and carbon dioxide.
  • Therefore; species X carries out aerobic respiration while species Y carries out anaerobic respiration.
