What are Advantages and disadvantages of pyramids of numbers?

Answer 1

Pyramids of numbers visually represent the number of organisms at each trophic level in an ecosystem, making it easy to understand the distribution of biomass. Advantages include clarity in illustrating population sizes and the ability to highlight ecological imbalances. However, a disadvantage is that they don't account for the size or biomass of organisms, potentially skewing the representation, as a few large organisms can dominate the pyramid despite lower overall numbers. Additionally, they can be less effective in complex ecosystems with numerous overlapping trophic interactions.
