The biomass pyramid is a very delicate balance that shouldn't be messed with. In the past it was realized that it is set up this way for a reason and an imbalance could really upset an ecosystem. The base of the pyramid is the widest and gets narrower the further you move up. Also, the bottom of the pyramid has a lot more energy with the primary producers, compared to the top with the carnivores. The four basic levels listed in the article are: primary producers, primary consumers, secondary consumers, and tertiary consumers. Biomass is measured in calories per square meter. The biomass in the Pyramid of Biomass decreases when you move from the bottom of the pyramid upwards.
