Energy Pyramid in Ecology: Trophic Levels and 10% Energy Transfer Rule #3529518 (License: Personal Use)

The diagram depicts a classic ecological energy pyramid, where primary producers (100%) capture solar energy, and each successive trophic level-primary (10%), secondary (1%), tertiary (0.1%), and apex predators (0.01%)-receives only about 10% of the energy from the level below. Green arrows show energy dissipated as heat at every level, while orange arrows indicate decomposition and nutrient recycling back to producers. The sun symbolizes the initial energy input, and the hexagon labeled “Decomposers” completes the cycle.

Used in biology and environmental science education to explain ecosystem energetics, food chains, and sustainability concepts; ideal for high school or college curriculum pages,科普 articles, or ecology resource hubs targeting learners seeking foundational ecological principles.
