Food Chain Pyramid Diagram: Energy Flow in Ecosystems #3529516 (License: Personal Use)

This diagram depicts a four-tiered ecological food pyramid powered by solar energy, where green producers (trees, grasses, ferns) form the base. Primary consumers (deer, rabbits, insects) feed on producers; secondary consumers (foxes, snakes, spiders) prey on them; and tertiary consumers (wolves, bears) sit at the apex. Red zigzag arrows indicate energy lost as heat at each transfer, emphasizing the 10% rule of energy efficiency.

Used in educational websites, biology textbooks, and environmental science resources to teach trophic dynamics, energy flow, and ecosystem structure. Matches user intent for learning foundational ecology concepts or preparing classroom materials.
