Chemosynthesis & Extremophiles

Most plants on land need the sun to make food, but deep in the ocean, it is pitch black. Instead of sunlight, some amazing creatures use chemicals coming out of the Earth's crust to make their energy. This is called chemosynthesis, and it is like cooking with rocks and heat instead of light. These extremophiles prove that life can find a way to thrive even in places where we thought it was impossible. It shows us that there are many different ways to be successful and alive.

Life can find a way to thrive even where we thought it was impossible. The sun is not the only way. The rules you were taught are not the only rules. Somewhere in the dark, something is thriving on what you threw away.

Chemosynthesis: biological conversion of carbon molecules using oxidation of inorganic compounds (hydrogen sulfide, ferrous ions) as energy source. Supports entire ecosystems independent of solar energy around hydrothermal vents and cold seeps. Revolutionized astrobiology: life could exist on icy moons like Europa or Enceladus with sub-surface oceans heated by tidal forces. The sun is optional. Life is not.

SOUND: The hiss of steam coming off a boiling kettle: Earth's kitchen.

SMELL: The smoky, burnt smell of a match being struck: chemistry at work.

TASTE: The sharp bite of a spicy pepper: energy without the sun.

TOUCH: Heat radiating from a warm stove: the Earth's inner fire.

SIGHT: A bright glow-stick shining in a dark room: light without the sun.

BODY: The energy you get after eating a quick snack: your body converting chemistry to motion.
