Can living things survive without the Sun?
Can some organisms survive without energy from the sun? Yes. Yes, there are some organisms we know of that live very deep in the ocean where light does not penetrate. These organisms use energy from chemical reactions and are called chemotrophs.
Is it possible to live in the ocean without light penetration?
Yes. Yes, there are some organisms we know of that live very deep in the ocean where light does not penetrate. These organisms use energy from chemical reactions and are called chemotrophs. There are a few different types of chemotrophs (see image below).
Do bacteria need the sun to survive?
It not only does not need the Sun but also does not need any other life. Most bacteria sponge off other species for some needs ¯ for example, bacteria around sea vents rely on planktonon the sea surface to produce oxygen from photosynthesis. Then sea-vent bacteria merely take oxygen from deep seawater put there by the surface-dwelling plankton.
What is the source of energy for living organisms?
These creatures, over millions of years, evolved to use energy supplied from our planet rather than our sun. Such organisms use inorganic chemicals (usually hydrogen and hydrogen sulfide obtained from rocks and sea water) for energy instead of organic matter. They utilize carbon dioxide as their carbon source.

Can any organisms survive without energy from the sun?
Can some organisms survive without energy from the sun? Explain your answer. YES. We call them chemotrophs/chemoautotroph.
What will happen to all organism without sunlight?
Without the Sun's rays, all photosynthesis on Earth would stop. All plants would die and, eventually, all animals that rely on plants for food — including humans — would die, too.
Why do organisms need sunlight?
The Sun is the major source of energy for organisms and the ecosystems of which they are a part. Producers, such as plants and algae, use energy from sunlight to make food energy by combining carbon dioxide and water to form organic matter. This process begins the flow of energy through almost all food webs.
How can organisms survive without sunlight photosynthesis?
However, in environments where there is no sunlight and thus no plants, organisms instead rely on primary production through a process called chemosynthesis, which runs on chemical energy. Together, photosynthesis and chemosynthesis fuel all life on Earth.
What effect would the lack of sunlight have on animals?
This comes with different consequences for animals. Lack of sunlight will lead to a Vitamin D deficiency, leading to a lack of absorption of calcium in them. It would weaken their bones and teeth.
How can some organisms survive without sunlight and photo synthesis?
How are some organisms able to survive without sunlight and photosynthesis? Some organisms are able to survive without sunlight and photosynthesis through similar processes, for example cellular respiration. Cellular respiration is the process of oxidizing food molecules, like glucose, to carbon dioxide and water.
What effect would the lack of sunlight have on plants animals and environment?
Without the sun, plants wouldn't get the necessary food needed to grow, reproduce, and survive. Plants need three basic things to live: sunlight, water, and carbon dioxide. Through a process called photosynthesis, the plants use the energy from the sun to convert carbon dioxide, soil nutrients, and water into food!
How do nocturnal animals survive without sunlight? - Quora
Answer (1 of 3): To start off, lets put out a few factors to prevent confusion: Yes, all animals do need vitamin D, it is essential for bone growth and calcium/phosporus levels in bones as well as immune strength and neuromuscular function. “But what if you don’t have bones, like a cartilaginous ...
5 Underground Animals That Rarely See the Light of Day - SunnySports Blog
Although people rarely see them, the earth is filled with underground animals who may never see sunlight for the entirety of their existence. Many of these creatures simply never come out of their burrows; however, some are nocturnal and may be seen, if only for a moment, under the cloak of night.
If our ozone layer was almost non-existent, what would happen?
I’m aware that plant life would die except for things like really big trees, but even those would die off eventually. Then herbivores would die off …
These bacteria use radiated water as food: IU News Room: Indiana University
Researchers from Indiana University Bloomington and eight collaborating institutions report in this week's Science a self-sustaining community of bacteria that live in rocks 2.8 kilometers below Earth's surface. Think that's weird? The bacteria rely on radioactive uranium to convert water molecules to useable energy.
What do organisms use for energy?
These creatures, over millions of years, evolved to use energy supplied from our planet rather than our sun. Such organisms use inorganic chemicals (usually hydrogen and hydrogen sulfide obtained from rocks and sea water) for energy instead of organic matter. They utilize carbon dioxide as their carbon source.
How far can thermophiles survive?
These thermophiles never see the Sun or encounter a breath of oxygen, but survive 2.4 kilometers (1.5 mi) below the sea surface.
What do vent organisms eat?
Sometimes vent organisms also eat the vent bacteria or their waste products. Dax' cousins thus contribute nutrients to the vent community and form the base of the food web. These thermophiles never see the Sun or encounter a breath of oxygen, but survive 2.4 kilometers (1.5 mi) below the sea surface.
How much carbon does a living thing have?
Carbon is the key. "The concentration of carbon in living matter (18 per cent) is almost 100 times greater than its concentration in the Earth (0.19 per cent). So living things extract carbon from their nonliving environment," says biologist John W. Kimball , author of Biology. Given energy, though, organisms can do the extraction work.
What is the primary function of all organisms?
When a creature successfully manages to reproduce, it has done its job. The task, though, can be difficult, especially along the fringes of the web of life - in the deep dark.
Where does life get its energy?
Almost all life on Earth is part of a web that gets its energy ultimately from the Sun. Each life form in the web usually exchanges nutrients with other life forms. But, if the environment can supply basic needs, strange singular forms can exist independently of all other life and even of the Sun.
Do living things extract carbon from their environment?
So living things extract carbon from their nonliving environment," says biologist John W. Kimball , author of Biology. Given energy, though, organisms can do the extraction work. How cells manage to survive without the Sun. You ask specifically about those animals that live in the deep dark of rock or sea.
