What are the primary producers of deep sea hydrothermal vent?
Solution : The primary producers of the deep – sea hydrothermal vent ecosystem are archaebacteria. These hace chemosynthetic mode of nutrition. Thus, option (b) , i.e. chemosynthetic bacteria is correct.
What are the primary producers in vent communities?
Chemosynthetic bacteria are the primary producers and form the base of vent food webs. All vent animals ultimately depend on the bacteria for food.
What is the producer in a hydrothermal vent?
While the primary producers in sunlit areas of the ocean are green plants, the primary producers in hydrothermal vent communities are chemosynthetic bacteria.
What is the primary source of food in deep sea hydrothermal vent communities?
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.
What type of producers is present in the deep part of the ocean?
In the ocean, algae, phytoplankton and kelp are producers.
What is the source of energy for deep sea hydrothermal ecosystem?
The three main sources of energy and nutrients for deep sea communities are marine snow, whale falls, and chemosynthesis at hydrothermal vents and cold seeps.
What is the primary source of energy for hydrothermal vent communities?
Hydrogen sulfide is the primary energy source for hot vents and cold seeps. Chemosynthesis is a process special bacteria use to produce energy without using sunlight. The energy comes from the oxidization of dissolved chemicals which escape from the Earth's crust through hydrothermal vents.
What is deep sea hydrothermal vent ecosystem?
Deep hydrothermal vents are like hot springs on the sea floor where mineral-rich, hot water flows into the otherwise cold, deep sea. Complete ecosystems sprout up around these vents, and numerous organisms are supported by the energy given off at these rare sites.
What are the decomposers in hydrothermal vents?
Decomposers feed on the smaller particles left behind from carnivores, scavengers and detritus feeders, as they break down nutrients to simpler forms that can be taken up by primary producers. At deep sea vents, decomposers are mainly bacteria, archaea and, possibly, sea urchins.)
What is the source of energy in deep sea hydrothermal ecosystem?
The three main sources of energy and nutrients for deep sea communities are marine snow, whale falls, and chemosynthesis at hydrothermal vents and cold seeps.
What type of organisms live in hydrothermal vents?
Hydrothermal vents are home to many kinds of animals, including tubeworms, crabs, mussels, and zoarcid fish. The octopus is one of the top predators in hydrothermal vent ecosystems. Most hydrothermal vents on the Mid-Atlantic Ridge don't have tubeworms, but they do have shrimp, many of which host symbiotic bacteria.
What is primary production in the sea?
Primary production is the creation of new organic matter from inorganic substrates, and it is this organic matter that serves as the base of the food web for most marine consumers.
What are 3 producers in the ocean?
Are jellyfish consumers or producers?
| TL | Example species | Trophic class |
|---|---|---|
| 4 | scads herring flyingfish | Secondary consumer |
| 3 | predatory copepods jellyfish amphipods | Secondary consumer |
| 2 | Rotifers filter-feeding copepods | Primary consumer |
| 1 | Diatoms dinoflagellates | Primary producer |

Why are there no producers in the deep-sea ecosystem?
After the aphotic zone, there's complete darkness. From 1,000 meters below the surface, all the way to the sea floor, no sunlight penetrates the darkness; and because photosynthesis can't take place, there are no plants, either.
What is the source of energy in deep ocean for plants?
Thus, the energy source that sustains this deep-ocean ecosystem is not sunlight but rather the energy from chemical reaction (chemosynthesis).
What is the primary source of food in deep-sea hydrothermal vent communities quizlet?
2. Deep-sea vent communities depend on specialized autotrophs that extract the exceedingly dim light that filters down to that depth and use it as a specialized form of photosynthesis to produce carbohydrates.
Are there any plants in hydrothermal vents?
Organisms that live around hydrothermal vents don't rely on sunlight and photosynthesis. Instead, bacteria and archaea use a process called chemosynthesis to convert minerals and other chemicals in the water into energy.
What plants live in hydrothermal vents?
Instead of the characteristic tubeworms, mussels and shrimp found along the main mid-ocean ridge system, these East Scotia Ridge vents appear to be home to anemones, limpets, snails, stalked barnacles, and sea spiders. The dominant species is a new species of Yeti Crab in the genus Kiwa.
How do producers near deep sea vents obtain energy?
Explain how producers near deep-sea vents obtain energy. They obtain energy by using energy in hydrogen sulfide from the vents.
Which of the following is the primary producer in the hydrothermal vent food web?
What are the primary producers in hydrothermal vents? The chemosynthetic bacteria forms a thick layer on the sea bed and attracts many other organisms to feed on them. These chemosynthetic bacteria form the base of the food chain as they are the primary producers of the deep sea hydrothermal vent ecosystem.
What organisms live in deep sea vents?
Animals such as scaly-foot gastropods (Chrysomallon squamiferum) and yeti crabs (Kiwa species) have only been recorded at hydrothermal vents. Large colonies of vent mussels and tube worms can also be found living there. In 1980, the Pompeii worm (Alvinella pompejana) was identified living on the sides of vent chimneys.
What energy source do deep-sea organisms at hydrothermal vents use for survival?
Organisms that live around hydrothermal vents don't rely on sunlight and photosynthesis. Instead, bacteria and archaea use a process called chemosynthesis to convert minerals and other chemicals in the water into energy.
What bacteria live in deep sea vents?
Green sulfur bacteria are unique among hydrothermal vent bacteria because they require both chemical energy (from hydrogen sulfide) and light energy to survive.
Is the primary producer?
Autotrophs or primary producers are organisms that acquire their energy from sunlight and materials from nonliving sources. Algae, higher plants, and some bacteria and protists are important autotrophs in running waters. Heterotrophs obtain energy and materials by consuming living or dead organic matter.
Which of the following is a primary producer?
The correct answer is Green plants.
Is plankton a primary producer?
They are what is known as primary producers of the ocean—the organisms that form the base of the food chain. Because they need light, phytoplankton live near the surface, where enough sunlight can penetrate to power photosynthesis.
Are diatoms primary producers?
Diatoms are one of the major primary producers in the ocean, responsible annually for ~20% of photosynthetically fixed CO2 on Earth.
Are there producers in the deep sea?
Deep Ocean Primary Producers The primary producers of the deep oceanic zones are typically bacteria. Animals living in these harsh zones rely on eating bacteria to survive in the same way that animals rely on plants in the light-accessible zones of Earth.
Why are there no producers in the deep sea ecosystem?
After the aphotic zone, there's complete darkness. From 1,000 meters below the surface, all the way to the sea floor, no sunlight penetrates the darkness; and because photosynthesis can't take place, there are no plants, either.
What is the main source of energy in the ocean?
Solar Energy Most of the ocean's energy comes from the sun – currents, waves, and winds all are a result of the sun's radiant energy. This large expanse of ocean surface can be used to produce electricity with photovoltaics (PV).
