Organisms that are without the presence of oxygen revert to fermentation. It is important to note, however, that organisms that rely heavily on respiration (and therefore oxygen) cannot survive for long periods of time with just fermentation. In an attempt to create as much ATP as possible (only 2 ATP created in fermentation with anywhere from 30-36 created during respiration) an excess of lactic acid will build up.
Organisms that are experiencing a lack of sunlight, or are at risk of dehydration if their pores are opened (plants in hot/dry climates), use alternate methods of photosynthesis in order to take in CO2 without also losing all of their water stores (known as C3 and C4 plants because of the number of carbons linked together during the Calvin cycle).
BY Blocking the Sunlight and Depleting oxygen
Most need the following: Sunlight Oxygen Water Soil Habitat
Photosynthesis uses, water + carbon Dioxide in the presence of sunlight for energy, to convert the reactants into Oxygen and Glucose. Without sunlight at night time, plants use stored energy from the day, but when incapable of supplying more energy, revert to respiration to breathe.
Aerobic organisms use oxygen.
It would be impossible for oxygen requiring organisms to exist before photosynthetic organisms because there was not oxygen in the atmosphere for these organisms to breathe. Photosynthetic organisms take carbon dioxide and water in and create oxygen as waste. Before these photosynthetic organisms existed there was not enough or any oxygen in the atmosphere for organisms requiring oxygen to survive.
Autotrophs
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.
Because of lack of oxygen and sunlight.

Producers are organisms that make their own food using sunlight (photosynthesis) consumers are organisms that eat producers or other consumers and decomposers are organisms that return the dead organisms to their primary components such as oxygen, nitrogen, carbon dioxide

There are certain types of plants ( for e.g.) usually in very heavliy canopyed Jungles/Forests that require no sunlight? 1) Organisms that do not require O2 are generally poisoned by it - the Anaerobes - and 2) Organisms that thrive without sunlight are called Chemoautotrophs.
