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.
Photosynthesis is the
conversion of carbon dioxide and water into sugars and oxygen by bacteria- with help of light
conversion of methane gas and water into sugars and oxygen by plants - with help of light
conversion of carbon dioxide and water into sugars and oxygen by plants - with little to no light
conversion of carbon dioxide and water into sugars and oxygen by plants - with help of light
A difference between photosynthesis and chemosynthesis
Photosynthesis doesn't use light and chemosynthesis does
Photosynthesis makes sugar and chemosynthesis doesn't

What happens in the process of photosynthesis?
Plants transform energy from the sun into chemical energy.
Plants use oxygen to store energy in food.
Animals use chemical energy in food to carry out life functions.
Animals transform energy stored in sugar into energy stored in fat.
