In the ecological pyramid, the amount of potential food available for each trophic level a) remains the same. b) increases over time. c) decreases from bottom to top. d) increases from bottom to top

The correct answer would be C) decreases from bottom to top.

The population size or the number of organisms decreases significantly as we move up the food chain.

It is because less amount of energy is available at higher trophic levels due to ten percent law. Thus, the trophic level can sustain comparatively less number of organisms.

Consequently, the amount of potential food decreases as we move up the food chain.

For example, in a terrestrial food chain, the biomass of producers (first trophic level) is the highest whereas the biomass of lion is the minimum (last trophic level)
