A pyramid of numbers illustrates the numerical relationships between organisms in an ecosystem, which may not always align with the energy flow pyramid in terms of energy transfer.

Explanation:

Pyramid of numbers is a graphical representation of the number of individual organisms present at each trophic level in an ecosystem. If an ecologist models the relationship between bird parasites, blue jays, and oak trees in a hectare, the pyramid of numbers would have the base with the highest number of bird parasites, followed by blue jays, and oak trees at the top.

Energy flow pyramid represents the flow of energy through trophic levels in an ecosystem, where energy decreases with each higher trophic level. The pyramid of numbers may not always match the energy flow pyramid due to factors like size and productivity of organisms.
