What is the ultimate source of energy for the majority of life on earth?
Simplistically, the Sun (sunlight) is this ultimate energy source. BUT.... There are some ecosystems (those round black smokers in the deep oceans - or bacteria that live deep down in the solid rock of the earth) which use chemical energy produced by the heat within our planet as their energy source. organic food and its oxidation during respiration.
What is the primary source of energy for a food web?
The primary source of energy for almost all food chains is the sun. The usual series is that the sun provides energy to plants that provide to other creatures. Some ecosystems rely on other energy sources however. For instance some deep ocean ecosystems rely on geothermal energy harvested by bacteria.
What is the primary source of energy in all food chains?
The Sun is the primary source of all energy in nearly all food chains. However, some deep-sea ecosystems utilize heat from underwater thermal vents as their primary energy sources since sunlight is virtually nonexistent.
what is the source of all the food in the ecosystems?
The Sun and in the case of deep sea vents, the heat and chemicals from Earth's interior.
What is the major source of energy in deep sea producers?
chemosynthesis
Why cant deep water ecosystems rely on photosynthesis?
Deep water ecosystems cannot rely on photosynthesis because sunlight cannot penetrate to the depths where these ecosystems are located. Without adequate sunlight, plants and algae cannot carry out photosynthesis to produce energy, causing these ecosystems to rely on alternative energy sources such as chemosynthesis or detritus.
Is there a living thing that does not depend on plants?
Yes, some deep-sea ecosystems are based on chemosynthesis where bacteria use chemicals from hydrothermal vents to produce energy instead of relying on sunlight or plants. These ecosystems can support diverse life forms that do not depend directly on plants for their energy source.
What role do chemosynthetic bacteria play in deep-sea volcanic-vent ecosystems?
Chemosynthetic bacteria in deep-sea volcanic-vent ecosystems are essential because they are the primary producers. They convert chemicals in the vent fluids, such as hydrogen sulfide, into organic molecules through chemosynthesis, serving as the base of the food web for other organisms in these extreme environments. These bacteria support a diverse community of organisms by providing a source of energy where sunlight is not available.
What is a energy source for hydrothermal vent?
The heat from deep in the earth's mantle.
Is alternative energy renewable ecologically safe source of energy?
Renewable energy doesn't get used up, in the way that coal and oil do. It is still there the next day, such as sunshine; wind power; water power from rivers and oceans; and geothermal power, which uses the heat deep below the surface of the earth. They are also called the Alternative energy sources.
How can you compare mountains and oceans?
Oceans are deep, mountains are tall.
What is the primary source of energy for organisms that live near deep-sea vents?
hydrogen sulfide
