Chemosynthesis

Chemosynthesis is a process by which organisms produce food without sunlight, using chemical reactions. It occurs in deep-sea environments like hydrothermal vents, where bacteria convert hydrogen sulfide and methane into glucose. This process supports life forms such as tubeworms, which have adapted to thrive in these harsh conditions. While not all organisms rely on chemosynthesis, it is crucial for those in sunless environments.

What is chemosynthesis and how do organisms use it to make their own food?

Describe the role of hydrogen sulfide in the process of chemosynthesis.

How do tubeworms and other animals survive in environments with poisonous chemicals?

Explain the process by which microbes convert carbon dioxide into sugars during chemosynthesis.

Why is chemosynthesis considered an important process for organisms without access to sunlight?
