Ecological Pyramids Explained: Energy, Biomass, and Numbers #3529524 (License: Personal Use)

The left panel illustrates the energy pyramid, where only ~10% of energy transfers between trophic levels, with the rest lost as heat. The center panel depicts the biomass pyramid using real-world mass comparisons (grain → chicken → human), while the right panel shows the pyramid of numbers, highlighting how individual counts often decrease upward-even though exceptions like parasitic food chains exist.

Used in biology education (high school to college) to teach ecosystem dynamics; supports lessons on food chains, trophic efficiency, and sustainability. Matches user intent for visual learning and curriculum-aligned study aids.
