How Energy Flows From the Sun Through Every Ecosystem

The Sun: Life’s Power Source — Every ecosystem on Earth runs on solar energy — the ultimate fuel behind food, growth, and survival.
Photosynthesis Magic — Plants, algae, and some bacteria capture sunlight and turn it into sugar — nature’s first energy transfer.
The Energy Chain Begins — Producers store solar power, herbivores eat the plants, and carnivores feed on them — energy passes life to life.
The 10% Rule — Only about 10% of energy moves from one level to the next — the rest is used or lost as heat.
Decomposers Keep It Moving — When organisms die, fungi and bacteria recycle their stored energy back into the soil and atmosphere.
From Forests to Oceans — Whether it’s a rainforest canopy or a coral reef, all ecosystems rely on sunlight to keep the energy flowing.
Producers Set the Pace — The more sunlight captured by plants and plankton, the more energy available for everything else in the web of life.
Heat Loss = Balance — As energy spreads and dissipates, it keeps ecosystems from overloading — nature’s built-in energy regulator.
Human Energy Connection — Our food, fuels, and even oxygen trace back to photosynthesis — every meal is sunlight in disguise.
The Endless Cycle — The Sun rises, energy flows, and life continues — a daily rhythm that powers every heartbeat on Earth.
