Front

Define chemosynthesis.

Back

A process by which certain organisms convert chemical energy from inorganic molecules into organic matter.

Front

What is the primary energy source for organisms living near hydrothermal vents?

Back

Chemical energy from hydrogen sulfide.

Front

What adaptations do deep-sea organisms have for survival in extreme conditions?

Back

Adaptations include specialized feeding mechanisms, pressure resistance, and unique metabolic processes.

Front

What is the significance of hydrothermal vents in marine ecosystems?

Back

They provide a unique habitat and energy source for diverse organisms, supporting complex food webs.

Front

How do deep-sea organisms contribute to the carbon cycle?

Back

They play a role in carbon fixation through chemosynthesis, converting inorganic carbon into organic matter.
