Ocean Zones & Ecosystems

Front

What are hydrothermal vents?

Back

Hydrothermal vents are fissures in the ocean floor that release geothermally heated water.

Front

How do hydrothermal vents support unique ecosystems?

Back

They provide a habitat for organisms that can withstand extreme temperatures and high levels of minerals.

Front

What are ocean basins?

Back

Ocean basins are the largest depressions on earth.

Front

How does temperature vary in different ocean zones?

Back

Temperature varies due to factors such as sunlight, depth, and currents.

Front

What is the impact of temperature variation on marine life?

Back

It influences species distribution and metabolic rates.

Front

What animals live in the disphotic zone of the ocean?

Back

Animals such as shrimp, cuttlefish, squid, and jellyfish inhabit the disphotic zone.

Front

What is chemosynthesis?

Back

Chemosynthesis is the process by which organisms use chemical energy to produce food, instead of using sunlight.

Front

What types of organisms rely on chemosynthesis near hydrothermal vents?

Back

Organisms such as certain bacteria and archaea rely on chemosynthesis as food chain producers.

Front

What is the photic zone?

Back

The photic zone is the upper layer of the ocean where sunlight penetrates, allowing photosynthesis to occur.

Front

What is the aphotic zone?

Back

The aphotic zone is the part of the ocean where sunlight does not reach, making photosynthesis impossible.
