Food Chain Diagram: Energy Flow from Plants to Owl via Caterpillar and Snake #78009 (License: Personal Use)

This educational diagram illustrates a simple linear food chain in a forest ecosystem: photosynthetic leaves are consumed by a caterpillar (primary consumer), which is preyed upon by a snake (secondary consumer), and finally the snake is hunted by an owl (tertiary consumer). Blue arrows also show how dead organisms and waste are broken down by decomposers-including bacteria, fungi, and detritivores-releasing nutrients that nourish the leaves, completing the cycle.

Used in biology or ecology educational materials (e.g., K-12 science textbooks, online learning modules, museum exhibits) to teach trophic levels, energy flow, and nutrient cycling; matches user intent to understand basic ecosystem dynamics visually.
