Here, we have investigated how microbial communities and chemical energy availabilities vary along cross … Some vent fields may remain active for 10,000 years, but individual vents are much shorter-lived. Chemosynthetic bacteria obtain energy from the chemical bonds of hydrogen sulfide. In hydrothermal vent communities, these bacteria are the first step in the food chain. Microorganisms are the chief primary producers within present-day deep-sea hydrothermal vent ecosystems, and play a fundamental role in shaping the ecology of these environments. However, very little is known about the microbes that occurred within, and structured, ancient vent communities.

In hydrothermal vent communities, these bacteria are the first step in the food chain. to form hydrothermal vent structures (Klevenz et al., 2011). Chemosynthetic primary producers allow communities at hydrothermal vents to thrive.

This paper reviews the present knowledge on the primary consumers from the hydrothermal vent community discovered in three different sites of the eastern Pacific (namely Galapagos ridge, East Pacific Rise at 21° N and 13° N). They display uniform ecological structure and zoological composition. Two of the species that inhabit a hydrothermal vent are Tevnia jerichonana, and Riftia pachyptila.

All other life depends on primary producers, and they have the greatest biomass in the community. While the primary producers in sunlit areas of the ocean are green plants, the primary producers in hydrothermal vent communities are chemosynthetic bacteria. 2.

As there are many examples of primary producers, two dominant types are coral and one of the many types of brown algae, kelp. Photosynthesis. Gross primary production occurs by photosynthesis. The team estimates that deep-sea hydrothermal vent microbial communities produce in excess of 4,000 tons of organic carbon every day, worldwide—about as much carbon as you’d find in 200 blue whales.

Chemosynthetic primary producers allow communities at hydrothermal vents to thrive. This all ties back into the formation of the vents, as this is the source of high energy inorganic compounds that are used for subsistence by these chemosynthetic organisms. Created Date: 11/6/2012 3:03:35 PM The hydrothermal vent food web below has four layers: Primary producers are the original source of food in the vent ecosystem, using chemical energy to create organic molecules. All other life depends on primary producers, and they have the greatest biomass in the community. Primary consumers get their energy directly from the primary producers Hydrothermal Vents - David Attenborough Hydrothermal vents support life; this demonstrates just how resilient life can be. There are also a surprising diversity of life forms that inhabit these vents, despite the absence of sunlight and elevated pressures and deadly heat.
