- 1. Multiple Choice
Chemosynthesis is the
conversion of carbon into sugars and nutrients by bacteria in dark places. They use hydrogen gas, hydrogen sulfide and methane gas as a source of energy, relies on sunlight.
conversion of carbon into sugars and nutrients by bacteria in dark places. They use hydrogen gas, hydrogen sulfide and methane gas as a source of energy, rather than sunlight.
conversion of carbon into sugars and nutrients by bacteria in dark places. They use hydrogen gas, hydrogen sulfide and methane gas as a source of energy, with little to no sunlight.
conversion of carbon into sugars and nutrients by bacteria in dark places. They use hydrogen gas, hydrogen sulfide and methane gas as a source of energy, with some sunlight.
