Both pyramids show more organisms at lower levels and fewer at higher levels. Pyramid A has more organisms at all levels than B, likely due to the difference in top predators (hawk vs. omnivorous blue jay).
Similarities
Both pyramids in Model 2 are pyramids of numbers, which show the number of organisms at each trophic level in a food chain.
They both have four trophic levels: primary producers, primary consumers, secondary consumers, and tertiary consumers.
Both pyramids show that there are more organisms at the lower trophic levels and fewer organisms at the higher trophic levels.
Differences
Pyramid A has a hawk at the top trophic level, while Pyramid B has a blue jay at the top trophic level.
Pyramid A has more organisms at each trophic level than Pyramid B. For example, Pyramid A has 1000 caterpillars at the secondary consumer level, while Pyramid B has 1000 caterpillars at the primary consumer level.
Overall
The two pyramids in Model 2 are similar in that they are both pyramids of numbers and they both show that there are more organisms at the lower trophic levels and fewer organisms at the higher trophic levels. However, they differ in the number of organisms at each trophic level and the type of organism at the top trophic level.
