Is a pyramid of biomass the same as a food pyramid?

Answer 1

No, the two are not the same.

When we refer to the food pyramid, we are referring to guidelines for healthy eating for humans. You can see an example of what a food pyramid traditionally looks like below.

Whereas a biomass pyramid or an energy pyramid refers to the amount of biomass, the total mass of organisms within a certain area, available for consumption.

Producers are found on the bottom of the pyramid because there are the most of them. There are a huge number of photosynthetic vegetation that relies on the sun for energy. These plants then support the animals that consume them, primary consumers or herbivores. There are fewer herbivores than there are producers. Next up the pyramid, there are even fewer predators who consume the herbivores.

No, a pyramid of biomass represents the total mass of living organisms at each trophic level within an ecosystem, while a food pyramid illustrates the flow of energy through different trophic levels in a food chain.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
