Consider the following statements about hydrothermal vents.

1.Underwater volcanoes at spreading ridges and convergent plate boundaries produce hot springs known as hydrothermal vents.

2.Hot seawater in hydrothermal vent boils because of excessive high temperature present there.

3.These regions are completely barren and thus no organism can be found here.

Explanation:

1 only

Hydrothermal vents are indeed associated with underwater volcanic activity, specifically at spreading ridges and convergent plate boundaries. Hot springs are produced at these locations.

However, hot seawater in hydrothermal vents does not necessarily boil. The high pressure at the depths of the ocean can keep the water from boiling even at elevated temperatures.

Hydrothermal vent regions are not completely barren. They are, in fact, teeming with life, including unique and extremophilic organisms adapted to the harsh conditions of high pressure, high temperature, and the chemical composition of the vent fluids.

So, the correct answer is "1 only."
