Energy Pyramid in Grassland Ecosystems | Food Chain & Trophic Levels Explained #3529521 (License: Personal Use)

The diagram depicts a classic ecological energy pyramid for a grassland ecosystem, starting with cacti as producers that capture solar energy, followed by mice (primary consumers), snakes (secondary consumers), and hawks (tertiary consumers). Arrows indicate energy input from the sun, energy passed upward (blue), and energy lost as heat or used at each level (red), reflecting the 10% rule of energy transfer efficiency.

Used in educational biology resources, ecology lesson plans, and environmental science websites to explain trophic dynamics and energy loss in food chains; matches user intent for learning about ecosystem structure and sustainability principles.
