Which statement describes the relationship between the law of conservation of energy and the energy pyramid shown?
a. The population of herbivores in an energy pyramid exceeds that of autotrophs because herbivores consume all their necessary energy from plants.
b. The sun provides 10% of the energy needed for autotrophs to survive and occupies the lowest level in the energy pyramid.
c. The population of carnivores is always the greatest in an energy pyramid because they are at the top trophic level.
d. Ten percent of the energy available in energy pyramid trophic levels is transferred to the next trophic level.
