Biology · Secondary 4 · Medium · Pyramids of numbers and biomass

- Each tree has a much larger mass than a fox, so total biomass is higher for producers
- Biomass pyramids always have more levels than pyramids of numbers
- Biomass pyramids only include animals, not plants
- Pyramids of numbers cannot include top carnivores
