Animals and most microorganisms are classified as chemoorganoheterotrophs. The prefixes "chemo," "organo," and "hetero" refer to how the organism meets its needs, respectively, for: Choose one: A. carbon, electrons, and energy B. energy, electrons, and carbon C. electrons, carbon, and energy D. carbon, energy, and electrons E. electrons, energy, and carbon

B. energy, electrons, and carbon

Explanation:

chemoorganoheterotrophs animals and organisms derive energy, electrons and carbon from utilization of organic compounds.  

The prefix "chemo" these organisms derive their energy from chemical reactions, not light reaction, like plants that make use of photosynthesis.

The prefix "organo" means the source of the organism's energy is organic, not inorganic.

The prefix "hetero" shows that the organism needs carbon for the production of  biomass production.

the cladogram shown here shows similarities and differences among several classes of vertebrates. anatomically, the four have limb structure as their common ancestor. we might separate the mammals from the other three classes because they a) divergent; do not lay eggs b) identical; are warm-blooded c) varied; a four chambered heart d) homologous; have mammary glands
