deep sea vent community food web

Growth continues as long as there is a supply of hydrothermal fluid. Around 400 different kinds of animals are found at vents including tube worms, giant clams, mussels, crabs, shrimp and starfish all at varying levels of the food chain, with chemoautotrophic bacteria at the bottom (figure 911). FIGURE 9 – VENT FOOD WEB. Food chains start with a primary producer. The primary marine food web, which is based on plant productivity, includes many of the sea's species—but not all of them. Some vent fields may remain active for 10,000 years, but individual vents are much shorter-lived. Serpulid, or “feather duster” worms, and tevnia tubeworms, which are often the food of choice for vent crabs, the top predator of the vent community. Primary producers (organisms that make their own food from sunlight and/or chemical energy from deep sea vents) are the base of every food chain - these organisms are called autotrophs. Trophic Levels: The trophic level of an organism is the position it holds in a food chain. Chemosynthetic bacteria obtain energy from the chemical bonds of hydrogen sulfide. A food chain is the sequence of who eats whom in a biological community (an ecosystem) to obtain nutrition.

Vents have been located at depths varying from 1500 to 4000 meters. Sievert adds that these techniques are helping scientists to shed more light on interactions among organisms in vent food webs. A food chain is a set of linkages that show who eats who in an ecosystem and the transfer of energy that takes place. Whilst it was a surprise to find bacteria tolerating extreme temperatures, most They also realized that an entirely unique ecosystem, including hundreds of new species, existed around the vents. Life on a hydrothermal vent Primary producers: the base of the food web The scientists had made a fascinating discovery—deep-sea hydrothermal vents. A food chain starts with the primary energy source, usually the sun or boiling-hot deep sea vents. The hawksbill sea turtle is an omnivore, feeding on sea urchins, mollusks, crustaceans and algae. Bathymodiolus deep sea mussels, which are often the first creatures to colonize the vent and are able to survive for a short time after the vent is inactive. Some vents produce "white smokers". The answer is chemosynthetic bacteria in deep sea vents, which use chemicals instead of sunlight to make their own food. Decomposers are bacteria that chemically break down organic matter. They're the producers of this ecosystem. In hydrothermal vent communities, these bacteria are the first step in the food chain. They are also helping them assess the role of deep-sea vents in cycling chemicals such as carbon, nitrogen, and sulfur between rocks, the ocean, and living things. 2.
