Answer:
Option A, Strangler fig
Explanation:
The bottom most species in a food web is the producer or any other organism that contains chlorophyll and is able to produce food for themselves as well as other species. The species feeding on producer gets only 10% of the total energy contained within the producer and like wise energy at each trophic level of an energy pyramid is just 10% of its previous level.
Therefore species lying at the end of food web (apex of energy pyramid or highest trophic level) has the least energy and the species that lies at the bottom of food web (lowest level of energy pyramid or lowest trophic level)has the highest energy.
Hence, Strangler fig stores the most energy of all given options.
