Answer:
B. energy, electrons, and carbon
Step-by-step 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.
