- True or False: Among the three types of ecological pyramids, the most useful is the pyramid of biomass because it shows how much kilocalories are available at each trophic level.The trophic pyramid has very few large predators at the top and increasing numbers of creatures as you go to lower levels of the food chain. Why is that? If there are lots of prey animals in a system why aren’t there just as many predators? what is the difference between bottom up control and bottom down control?At which point in the trophic pyramid is the greatest arount (not percentage) of energy lost? A) Between the primary producers and the primary consumers B) Between the primary consumers and the secondary consumers C)Between the secondary consumers and the tertiary consumers D) Between the secondary consumers and the primary producers
