In a typical trophic pyramid, organisms are categorized into different levels based on their roles in the ecosystem. Primary consumers are those that eat primary producers (usually plants or phytoplankton).
- Section A typically represents producers (like plants).
- Section B usually represents primary consumers (herbivores).
- Section C may represent secondary consumers (carnivores that eat herbivores).
- Section D likely represents tertiary consumers (top predators).
Given this structure, the correct answer would be:
Organisms in section B (assuming this section represents primary consumers, such as herbivores).
