Deep ocean technology has allowed scientists to discover and study organisms living near deep-sea vents. Unlike surface organism
s, these organisms survive on a food web based on chemosynthesis instead of photosynthesis. Deep-sea vent organisms live in complete darkness under extreme pressure. What are deep-sea vent organisms evidence of?
These organisms depend on sulphur coming form the vents.
Explanation:
A hydrothermal vent is a fissure on the seafloor and is geothermally heated by the hot magma from below. They exist due to the tectonic activity of the earth.
These hydrothermal vents are found along the mid-oceanic ridges They are located where the new crust is formed.
Most of the deep-sea creature tends to thrive in these vents. These creatures have adapted to the high temperature and pressure changes and mainly adapted through symbiosis.
They make use of sulphur gas coming from these vents to sustain themselves.
The deep-sea vent organisms are the evidence of evolution because these organisms evolve with the passage of time and able to survive the extreme environmental condition of the deep sea vent. Evolution is the change in the characteristics of a species with the passage of several generations and relies on the process of natural selection. This evolution helps the organisms to adopt the surrounding environment and able them to survive in it.
