The dense aggregations of animal and bacterial life at the deep-sea hydrothermal vents are supported, at least in part, by sulfide-energy-based primary productivity. Sulfide-oxidizing bacteria are found free-living in the vent waters, on the surface of basaltic rocks, and as symbionts within certain tissues of the large vent tube worms and bivalve molluscs.
Sep 28, 2016 Within vent and seep ecosystems, faunal communities are At seeps and vents, primary producers have distinct δ13C signatures (Table 2)
Chemosynthetic bacteria are the primary producers and form the base of vent food webs. All vent animals ultimately depend on the bacteria for food. How does a vent community develop? When a vent forms, new lava on the ocean floor around the vent becomes covered with a thick mat of bacteria. Despite their unusual nature, faunas based on chemosynthesis are tied together by food webs similar to those of better-known communities.

• The primary producers in hydrothermal vent communities are a wide variety of bacteria and Archaea that utilize sulfur, hydrogen, methane 2016-09-13 better-known communities. 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.

The fluffy white stuff on these rocks is biofilm made of millions of bacteria and the gooey slime they produce. Bacteria are the first organisms to colonize the area around a new hydrothermal vent. Deep-sea hydrothermal vents are considered to be one of the most spectacular ecosystems on Earth. Microorganisms form the basis of the food chain in vents controlling the vent communities. However, the diversity of bacterial communities in deep-sea hydrothermal vents from different oceans remains largely unknown. 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.

1. While the primary producers in sunlit areas of the ocean are green plants, the primary producers in hydrothermal vent communities are chemosynthetic bacteria. 2. A complex community of living things survives at hydrothermal vents without sunlight.
Primary producers in hydrothermal vent communities are: A) algae. B) eyeless shrimp. C) giant clams.
