What does a food pyramid show that a food chain doesn't?

A food pyramid shows that top animal for that food chain for certain animal just like a lion is top for land animals and sharks are top for marine animals. It also shows whether its a herbivore,carnivore, or a producer. The producers are the plants that the herbivore eats and the herbivore becomes the primary consumer which gets eaten by the carnivore which is a meat eater and is the second consumer and then gets eaten by the top tertiary consumer which is most likely a carnivore. All the info is in a pyramid is basically what type of eater is it and what kind of consumer it is
