How do deep-sea hot spring ecosystems work?

In what year were deep-sea hot springs discovered near the Galápagos Islands?

• 1977

• 1980

• 1985

• 1990

The role of chemosynthesis in deep-sea ecosystems is to:

• provide energy for deep-sea organisms

• produce oxygen for marine life

• support photosynthesis

• regulate water temperature

The main focus of the study on deep-sea hot spring ecosystems is:

• the biodiversity of marine life

• the chemical composition of the water

• the geological formations

• the impact of human activities

What is the temperature of the fluids emanating from the sub-seafloor?

• 24°C

• 100°C

• 200°C

• 300°C

Which microorganisms were most prevalent in all incubations?

• Bacteria

• Viruses

• Fungi

• Algae

The significance of the microbial composition varying under different conditions is:

• It affects the ecosystem's balance and function.

• It has no impact on the environment.

• It only affects human health.

• It is irrelevant to scientific studies.

Chemolithoautotrophs are organisms that obtain energy from:

• Sunlight

• Organic compounds

• Inorganic compounds

• Other organisms

DNA sequencing is:

• a method to determine the order of nucleotides in DNA

• a process of DNA replication

• a technique for protein synthesis

• a way to edit genetic information

Geothermal energy is a form of energy derived from what source?

• Solar radiation

• Wind currents

• Earth's internal heat

• Ocean tides

In-situ refers to a process or event occurring:

• in its original place

• after being moved

• in a laboratory

• in a controlled environment
