Organisms that are larger require the respiration of something like oxygen to capture enough energy to run themselves.
Nitrogen fixation. It can only be performed by a very small number of species of anaerobic bacteria.
Obligate anaerobes are poisoned by O2 and use fermentation or anaerobic respiration
Biology of organisms to small for the human eye to see. This can be anywhere from a single cell, to an organism with a very small number of them.
Sponges are normally stationary organisms, they attacj=h themselves to a surface when very small and grow in that same place.

If a species is endangered, the organism will be found in very small numbers.

'organisms' because they are living things, 'mirco-' means very small.
Aerobic respiration produces more energy than anaerobic respiration(about 25x more)
I think you are meaning if organisms don't need oxygen are they still living things? The answer would be yes they are. There are plenty of anaerobic bacteria around. Anaerobic meaning that it lacks oxygen. Bacteria are single cell organisms that are very much alive, but there was also a recent discovery in 2010 where they discovered a multicellular organism that doesn't require oxygen as well it's a species of Spinoloricus.
living things need other elements but very small amounts

very very small . for example MICROScopic organisms are so small that they may only be viewed under a magnifying glass.
No just very small ones
