Which of the following statements is a correct distinction between autotrophs and heterotrophs?

Correct answer: D. Autotrophs but not heterotrophs can nourish themselves begining with nutrients that are entirely inorganic

  • A. Only heterotrophs require chemical compounds from the environment
  • B. Cellular respiration is unique to heterotrophs
  • C. Only heterotrophs have mitochondria
  • D. Autotrophs but not heterotrophs can nourish themselves begining with nutrients that are entirely inorganic

Explanation

Autotrophs, but not heterotrophs, can nourish themselves beginning with CO2 and other nutrients that are inorganic. Heterotrophs depend on autotrophs either directly or indirectly.OPTION A: Autotroph needs chemical compound from environment.OPTION B: Cellular respiration is present in both not only heterotrophy as both of them requires energy in form of ATP which is formed by cellular respiration.OPTION C: Both have mirochondria in their cells which generates energy for cells and work as power house of cell.OPTION D: Autotrophs, but not heterotrophs, can nourish themselves beginning with CO2 and other nutrients that are inorganic.

About Bioenergetics

Cellular respiration explains how cells release energy from glucose through glycolysis, the link reaction, Krebs cycle and electron transport chain. It includes ATP production, substrate-level and oxidative phosphorylation, aerobic versus anaerobic respiration, and the roles of mitochondria, oxygen and fermentation in energy transfer.
