Mastering Energy Balance

Chemosynthesis is a process in which chemical energy powers the production of carbohydrates.

Chemosynthetic bacteria live around volcanic vents in the deep sea, deep within Earth's crust, in underground streams and caves, and buried in the mud of tidal flats.

Chemosynthetic primary producers are more common and live in more environments than expected.
