there is no answer for this question
Yes
There are none. No sunlight penetrates that deep, so there is no sunlight for photosynthesis. Instead, bacteria use chemosynthesis. They take the chemicals in the water shooting out of the vents, and make it into food.
Hydrothermal vents are commonly found near volcanically active places, areas where tectonic plates are moving apart, ocean basins, and hotspots. Vent organisms depend on chemosynthetic bacteria for food. The water from the hydrothermal vent is rich in dissolved minerals and supports a large population of chemoautotrophic bacteria.
The Hydrothermal Vent Crab lives in the Sunlight Zone.

In hydrothermal vent communities, the primary producers are chemosynthetic bacteria and archaea. These microorganisms use the chemicals, particularly hydrogen sulfide, emitted from the vents to synthesize organic matter through chemosynthesis, forming the base of the food web. They provide energy and nutrients to a variety of organisms, including tube worms, clams, and other invertebrates that rely on these producers for sustenance.
The base of the food web in deep-sea vent communities is typically chemosynthetic bacteria. These bacteria use chemicals from the hydrothermal vents to produce energy through a process called chemosynthesis. This energy is then transferred to other organisms in the food web.
Chemosynthetic bacteria and archaea form the base of the food chain.Round a hydro thermal vent, the source of energy is chemical (from Hydrogen Sulfide) rather than light. Specialised singe celled organisms from the bacteria and archaea (called chemotrophs) use the chemical energy to grow and then various more normal animals eat the bacteria.
Vent tubeworms provide a stable environment and chemical compounds for chemosynthetic bacteria to thrive while the bacteria convert chemicals from the hydrothermal vent into energy for the tubeworms. This symbiotic relationship allows both organisms to obtain essential nutrients and energy from an otherwise harsh environment.
If the hydrothermal vent closed up and the water became too cold for bacteria to produce their own food, the carnivores dependent on these bacteria would be indirectly affected as their food source diminishes. This would disrupt the entire food chain in the ecosystem leading to a decrease in population of these carnivores.
