Food Chain Diagram: Energy Flow and Nutrient Cycling in Ecosystems #3031150 (License: Personal Use)

This educational diagram depicts a classic linear food chain starting with solar energy powering photosynthetic grass (producer), which is consumed by a grasshopper (primary consumer), then a mouse (secondary consumer), a snake (tertiary consumer), and finally a hawk (apex predator). A curved arrow labeled “nutrients” shows decomposers breaking down dead matter and returning essential elements to the soil for reuse by plants.

Used in biology or ecology education materials-classroom slides, textbook figures, or science websites-to teach trophic levels, energy transfer, and ecosystem sustainability. Matches user intent to understand basic food web dynamics.
