What organism does not need sunlight or oxygen to live?
Yes it is possible and one of the best example is; Archaea.
Do all organisms need light?
Light, the essence of life itself. Light is the main source of energy for all living organisms. Plants, main sustainers of life, are crucial in this conversion process and need light for photosynthesis that enables them to make their own food and food for others.
What bacteria does not need sunlight?
-Bacteria that use hydrogen and iron as a source of energy are hydrogen bacteria and iron bacteria respectively. So, the correct answer is ‘They prepare their own food without the help of sunlight’. Note: Examples of chemosynthetic bacteria are beggiatoa, ferrooxidans, T.
Can some organisms survive without sunlight explain?
Can some organisms survive without energy from the sun? Explain your answer. YES. We call them chemotrophs/chemoautotroph.
Do animals need sunlight to live?
Answer 2: Animals don’t need energy from the sun, not directly anyway. Animals get energy from the food they eat. There are some ecosystems in the deep ocean that use geothermal energy, but we use sunlight, because we eat plants, or we eat things that themselves eat plants, etc.
How can some organisms 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. They are producers because they are able to obtain synthesize their food.
Does cyanobacteria require light?
Cyanobacteria derive energy through photosynthesis—hence the need for sunlight. They are also some of the oldest forms of life on the planet.
What type of organisms undergo photosynthesis without sunlight?
Algae, phytoplankton, and some bacteria also perform photosynthesis. Some rare autotrophs produce food through a process called chemosynthesis, rather than through photosynthesis. Autotrophs that perform chemosynthesis do not use energy from the sun to produce food.
What if there is no sunlight?
With no sunlight, photosynthesis would stop, but that would only kill some of the plants—there are some larger trees that can survive for decades without it. Within a few days, however, the temperatures would begin to drop, and any humans left on the planet’s surface would die soon after.
