Answer:
- Oak trees: primary producers
- Caterpillars: primary consumers
- Blue Jays: secondary consumers
- Hawks: tertiary consumers
Explanation:
A trophic pyramid, also known as ecological pyramid or energy pyramid, is a graphic representation that shows the relationships between different types of organisms (i.e., producers and consumers) at the trophic levels of an ecosystem. The primary producers are autotrophic organisms that obtain energy from sunlight and chemical compounds from nonliving sources (e.g., photosynthetic plants, algae, etc). The primary consumers are organisms that eat primary producers (e.g., herbivores), while secondary consumers are organisms that eat primary consumers (e.g., omnivores). Moreover, tertiary consumers are predators and/or omnivores that eat secondary consumers (e.g., hawks). Finally, decomposers (e.g., bacteria) are organisms that obtain nutrients and energy by breaking down dead organic material (i.e., dead organisms) at all trophic levels into nutrients.
