Food Chain Diagram Explained: Producers, Consumers, and Decomposers #3640842 (License: Personal Use)

This educational diagram maps a terrestrial food chain starting with green plants as producers, followed by a grasshopper (primary consumer), frog (secondary), snake (tertiary), and hawk (final consumer). Fungi act as decomposers, breaking down dead matter and returning nutrients to the soil, completing the cycle. Arrows indicate the direction of energy transfer under sunlight and precipitation.
