Which three statements are true about the energy flow in an ecosystem? a. the main source of energy for the ecosystem is the sun. b. producers convert radiant energy to chemical energy and provide for the entire ecosystem. c. energy flows from carnivores to herbivores. d. the maximum amount of energy is received at the highest trophic level. e. the maximum amount of biomass is present at the lowest trophic level.

The correct answer will be options A, B and E.

Explanation:

Energy flow is the directional path of transfer of energy from one organism to another through a biological food chain.

The autotrophs or producers are present at the lowest trophic level which are capable of converting the sunlight energy to chemical energy or food via photosynthesis, therefore, receives maximum energy so accumulate high amount of biomass.  

Energy flows in ascending manner usually from the lowest trophic level to highest trophic level that is from autotrophs to herbivore to carnivores in a food chain by a law called ten percent law. So, the carnivores at the highest trophic level receive less energy as compared to another trophic level.

Thus, options A, B and E is the correct answer.
