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

If these are the missing choices: a. to determine skin temperature, place the back of your hand against the patient's skin.b. determine body temperature by touching the patient's hands and feet.c. skin temperature will tell you very little about this patient's condition or well-being.d. the patient's skin temperature and color will likely be warm and red.my answer is: a. to determine skin temperature, place the back of your hand against the patient's skin. using the back of the hand to check for temperature rather than the palm is more effective because the back of the hand has more nerves that can feel and transmit the temperature than the palm.
