Which of the following characteristics differentiates an autotroph from a heterotroph? a. a heterotroph can only obtain its energy from an autotroph. b. an heterotroph can only obtain its energy from a heterotroph. c. an heterotroph must obtain its energy from a heterotroph or other autotroph heterotrophs only obtain their energy from the sun. d. a heterotroph must obtain its energy from a autotroph or other heterotroph. autotrophs only obtain their energy from the sun.

I believe the answer is D. A heterotroph must obtain its energy from a autotroph or other heterotroph. Autotrophs only obtain their energy from the Sun.

Autotroph consist of organism that capable of doing photosynthesis so they could produce their own food. Heterotroph is organism that couldn't produce food. They have to take the food from other organism. When heterotroph take food from plants/autotroph they will be similar to herbivore. When heterotroph take food from other heterotroph they will be similar carnivore

small, big, or no change could occur in the phenotype. it could cause something as simple as a cats ears to curl backwards or something as frighting as death. it could also occur in the protien-coding area and have an effect on that but no effect on the amino acids. what has to occur is a changing in the hox gene or the control gene.

homeostasis is the tendency towards a relatively stable equilibrium between interdependent elements, especially as maintained by physiological processes. and this is how it applies to the integumentary system. back to top. skin functions in homeostasis include protection, regulation of body temperature, sensory reception, water balance, synthesis of vitamins and hormones, and absorption of materials. when body temperature falls, the sweat glands constrict and sweat production decreases.
