Food Chain Pyramid Diagram - Ecosystem Energy Flow Explained #3529522 (License: Personal Use)

This educational diagram depicts a terrestrial food pyramid with four trophic levels: producers (grass, cactus, tree, flower), primary consumers (grasshopper, squirrel, butterfly), secondary consumers (frog, spider, lizard, fox), and tertiary consumers (owl, hawk). The sun at the apex symbolizes the ultimate energy source driving the entire system.

Used in biology and environmental science education to teach ecosystem structure, energy flow, and trophic relationships; ideal for K-12 and introductory college curricula where visual learning supports conceptual understanding.
