Technically there's no organism that doesn't need the sun.
Archaebacteria
amm... water creatures like octopus etc.
Archaea, a domain of single-celled microorganisms, includes species that can thrive in extreme environments without the need for oxygen or sunlight. These Archaea are known as extremophiles and can be found in places such as deep sea volcanic vents and salt flats.
Pretty much all organisms need oxygen or sunlight to live, I know trees do not need oxygen to live, and deep sea creatures like the giant tube worm does not need sunlight. ^^^The idiocy of this post almost gave me autism^^^ The real answer is yes most organisms need oxygen and or sunlight to live, but Archaebacteria do not need either. they oxidize sulfur and other easily oxidized materials to obtain energy.
Anaerobic
oxygen. It releases oxygen, but doesn't require it.
The organism added to the test tube was likely a photosynthetic organism, such as algae or a plant, that produces oxygen through photosynthesis in the presence of sunlight. The increase in oxygen observed over time is a result of this photosynthetic process where the organism uses sunlight to convert carbon dioxide and water into oxygen and glucose.
Yes,it generally require.Organisms generally respire aerobically
The organism added was likely a photosynthetic organism, such as algae or a plant. Photosynthetic organisms use sunlight to convert carbon dioxide and water into oxygen during photosynthesis. The increase in oxygen observed in the test tube is a result of this process taking place.
Anaerobic bacteria, such as certain types of archaea and some fungi, can survive and thrive without oxygen. These microorganisms obtain energy through processes that do not involve oxygen. Additionally, some deep-sea organisms, like certain tube worms and chemosynthetic bacteria, can live in environments without sunlight by utilizing chemicals as an energy source.
An organism that breathes a substance other than oxygen is known as an anaerobe. Anaerobes do not require oxygen for respiration and can use other substances such as sulfur or nitrogen compounds.
A plant makes glucose and oxygen out of CO2, hydrogen, sunlight, and chlorophyll. It releases oxygen and "eats' the glucose for energy.
