Food Chain Pyramid Diagram - Producers to Tertiary Consumers Explained #3640844 (License: Personal Use)

This educational diagram depicts a classic trophic pyramid with four levels: producers (e.g., corn, radishes, trees, cherries) at the base; primary consumers (deer, squirrel, grasshopper, rabbit) feeding on them; secondary consumers (snake, badger, frog, cardinal) preying on herbivores; and tertiary consumers (cougar, eagle) at the apex. Each level visually represents decreasing biomass and energy transfer efficiency (~10% per step).

Used in biology or environmental science curricula, textbooks, and educational websites to teach ecosystem structure, energy flow, and trophic relationships; targets students, teachers, and curious learners seeking foundational ecology knowledge.
