Food Chain Diagram: Understanding Ecosystem Energy Flow #3640829 (License: Personal Use)

This educational diagram depicts a classic grassland food chain: grass (producer) is consumed by a grasshopper (primary consumer), which is eaten by mice (secondary consumers), then snakes (tertiary consumers), and finally a hawk (final consumer). Fungi act as decomposers, breaking down dead organisms and returning nutrients to the soil, completing the cycle. Arrows indicate energy flow direction, while color-coded circles denote trophic levels.

Used in biology or ecology educational resources-classroom slides, science websites, or curriculum materials-to teach trophic dynamics, energy transfer, and ecosystem interdependence. Matches user intent for visual learning about food chains and ecological roles.
