chemosynthesis

Front

What is chemosynthesis?

Back

Chemosynthesis is the process by which certain organisms convert carbon-containing molecules (like hydrogen sulfide) into organic matter using energy derived from chemical reactions, rather than from sunlight.

Front

Where do sulfur bacteria typically live?

Back

Sulfur bacteria typically live near deep sea volcanic vents and inside tube worms.

Front

What is the main purpose of chemosynthesis?

Back

The main purpose of chemosynthesis is to make food.

Front

What is the primary difference between photosynthesis and chemosynthesis?

Back

Chemosynthesis uses chemicals (like hydrogen sulfide) to make food, while photosynthesis uses sunlight.

Front

What do both chemosynthesis and photosynthesis require?

Back

Both chemosynthesis and photosynthesis require energy.

Front

What is the role of hydrogen sulfide in chemosynthesis?

Back

Hydrogen sulfide serves as a source of energy and carbon for organisms that perform chemosynthesis.

Front

Can chemosynthesis occur in the absence of sunlight?

Back

Yes, chemosynthesis can occur in the absence of sunlight, as it relies on chemical energy rather than solar energy.

Front

What types of organisms typically perform chemosynthesis?

Back

Chemosynthesis is typically performed by certain bacteria and archaea, especially those found in extreme environments.

Front

How does chemosynthesis contribute to the ecosystem?

Back

Chemosynthesis contributes to the ecosystem by providing a food source for organisms in environments where sunlight is not available, such as deep-sea vents.

Front

What is the chemical equation for chemosynthesis?

Back

A simplified equation for chemosynthesis is: 6 CO2 + 6 H2O + 3 H2S → C6H12O6 + 3 H2SO4.
