What is unique about the producers in hydrothermal vent ecosystems low high energy budgets?

Utmost and dynamic compounds provinding an energy source without sunlight usage by high-temperature deep-sea oxidization of dissolved chemicalsfrom the Earth's crust is unique about the producers in hydrothermal vent ecosystems low high energy budgets.

Explanation:

Hydrothermal deep-sea vent ecosystems low high energy budgets are recently found compounds from actinomycetes, microorganisms associated with high-temperature venting flues.

The process is  called chemosynthesis, in which specific bacteria elicit energy and food from the hydrogen sulfide and heat from the mineral-rich water pouring out of the vents without the sunlight usage. Low estimates of bacterial and total microbial carbon might reflect a rapid turnover of high levels of free-living bacterial biomass in the vent ecosystem. These bacteria becomes the lowest level of the food chain in these ecosystems, nutritional resources and energy budgets for populations, upon which all other vent animals are dependent.

Hydrothermal vents are fissures in subduction zones, with heated by magma seawater coming up from them. The spreading site is due to two tectonic plates movement in the ocean crust.

Hydrothermal ecosystem energy and organic carbon productivity at the deep seafloor fields have been discovered in only four decades as an available energy source.

answer; /// the answer to the first question is (b) it began when people first deliberately seeds; /// and (d); // it gave people a steady food supple for the first time;

just don't strip down in public lol
