How do autotrophs and heterotrophs benefit one another within an ecosystem? A. Autotrophs produce oxygen and carbon dioxide for heterotrophs, which produce chemical energy for autotrophs.

B. Autotrophs synthesize ATP and other nutrients for heterotrophs, which produce oxygen for autotrophs.

C. Autotrophs fix carbon and produce oxygen for heterotrophs, which produce carbon dioxide for autotrophs.

D. Autotrophs transform chemical energy into radiant energy for heterotrophs, which fix carbon for autotrophs.

When in solution, a molecule that moves slowly across an artificial membrane moves rapidly across a plasma membrane. this molecule rapidly enters the cell regardless of whether its concentration is higher inside or outside the cell. using this information, which transport mechanism is most likely to be responsible for the movement of the molecule across a plasma membrane? view available hint(s)when in solution, a molecule that moves slowly across an artificial membrane moves rapidly across a plasma membrane. this molecule rapidly enters the cell regardless of whether its concentration is higher inside or outside the cell. using this information, which transport mechanism is most likely to be responsible for the movement of the molecule across a plasma membrane? active transportexocytosis
