Ocean Ecosystems - II

Hydrothermal vents are unique ecosystems located on the ocean floor, often along mid-ocean ridges where tectonic plates are moving apart. Discovered in 1977, these vents release superheated, mineral-rich water into the surrounding deep-sea environment. Despite the absence of sunlight, hydrothermal ven...

Deep in the ocean, hydrothermal vents form at mid-ocean ridges where water is heated by magma and becomes extremely hot.

These vents create one of Earth’s most unusual ecosystems, completely separate from that created by sunlight.

Instead of photosynthesis, life here depends on chemosynthesis, in which bacteria make food using chemic...
