Yes. There are organisms called anaerobic bacteria which do not need oxygen. To some organisms, called obligate anaerobes, oxygen is actually toxic. The first living things on Earth were obligate anaerobes.
Although many would suggest oxygen, and this answer is true for all larger animals, a review of all living organisms suggests some that live in the absence of oxygen:anaerobes some of which substitute sulfur for oxygen in their life processesfacultative organisms
The reason why the food that plants make is important not only to the plant themselves, but to other organisms, is because the nutrients that the plant makes from photosynthesis not only helps the plant but other organisms that feed off of the plant and the plant's nutrients.
Most organisms we find in the fossil record depend on oxygen to survive, but it is not necessary in the actual process of fossilization. In fact, a lack of oxygen would actually improve an organism's chance of being preserved, as it would hold back decay.
Water can be depleted of it's oxygen by a number of different ways. Short of putting the water in a vacuum and "sucking" the dissolved oxygen out, oxygen-breathing organisms such as fish take oxygen from the water through respiration, for example. It is unlikely a large body of water to become completely deoxygenated due to the presence of photosynthetic aquatic organisms (plants) and the fact that oxygen is also dissolved in the water at the water's surface.
All organisms need oxygen to live.
These organisms do not need oxygen. They are called anaerobes.
Oxygen
All living organisms need water to survive, because they have cells. With air, not all living organisms need air. Some forms of bacteria do not need oxygen to live, and others can't stand oxygen.
even plants and most of the living organisms need oxygen
Organisms use the oxygen they absorb from the air for their cells. The cells need this oxygen in order to carry out their functions.
Most living organisms need oxygen for aerobic respiration.
Aquatic organisms need oxygen to survive
Organisms that need oxygen to survive are known as obligate aerobes. These organisms require oxygen for their metabolism and cellular respiration to produce energy. Examples include humans, most animals, and many types of bacteria.
Yes. There are organisms called anaerobic bacteria which do not need oxygen. To some organisms, called obligate anaerobes, oxygen is actually toxic. The first living things on Earth were obligate anaerobes.
The need for energy drives organisms to carry out cellular respiration, which uses oxygen to produce energy in the form of ATP. This consumption of oxygen by organisms in respiration is a key process in the oxygen cycle. Without this demand for oxygen to produce energy, the cycling of oxygen between the atmosphere and living organisms would not occur at the same rate.
No, not all multicellular organisms need oxygen for their cells to get energy. Some organisms, like anaerobic bacteria, can generate energy without oxygen through processes like fermentation. Additionally, some multicellular organisms, like certain deep-sea creatures, have evolved adaptations to survive in low-oxygen environments.
