A) having a single species of herbivore feeding on each plant species
B) increased extinction rates of species in the food chain

If there is a decrease in the amount of energy in a trophic level that is lost as it passes to the next higher level, then more energy will be available for organisms at higher trophic levels to consume. This could potentially lead to the development of longer food chains as more species may be able to sustain themselves on the available energy. The other choices listed would not necessarily increase the length of a food chain.
