Trophic Pyramid Diagram - Ecosystem Energy Flow Explained #3529515 (License: Personal Use)

This educational illustration depicts a four-level trophic pyramid: primary producers (grasses, algae), primary consumers (grasshoppers, caterpillars), secondary consumers (mice, lizards), and tertiary consumers (owls). Each level represents decreasing biomass and energy availability, highlighting ecological efficiency and food chain dynamics. The painted crow at the apex symbolizes a top predator in many terrestrial ecosystems.

Used in biology textbooks, ecology lesson plans, and environmental science websites to teach food chains, energy pyramids, and ecosystem structure; targets students, educators, and nature enthusiasts seeking foundational ecological knowledge.
