Choose 1
Choose 1
(Choice A)
A
After energy enters the ecosystem via photosynthesis, energy flow stops, because all other major metabolic processes require oxygen.
(Choice B)
B
Energy flow occurs as organisms carry out anaerobic respiration, which does not require oxygen.
(Choice C)
C
Energy flow occurs as organisms use aerobic cellular respiration, which requires only carbon dioxide.
