The word anaerobic is from the French word, anaérobie, coined by Louis Pasteur in 1863. It is from the Greek an- ("without") + aer ("air") + bios ("life"). The opposite word is "aerobic," meaning requiring oxygen or air.
In humans, anaerobic organisms are typically found in the gastrointestinal tract. Some anaerobic bacteria produce important toxins.Learn more about Biology
Photosynthesis plays an important role in the environment for several reasons as it helps clean the air because plants use the carbon dioxide in the air for photosynthesis, the plants produce oxygen as a by-product which all humans and animals need to live and it also makes plants grow, providing food for animals that feed on plants. Without plants, the world would quickly become uninhabitable for human and animal life. The oxygen would be used up and there would be no food to feed the animals that humans rely on for food.Full Answer >

An aerotolerant anaerobe is an organism that tolerates the presence of oxygen but does not require it for growth. Instead, aerotolerant anaerobes use fermentation to survive. An example organism is lactobacillus, a bacteria that lives in the gut of humans and is also used in the production of yogurt.Full Answer >
Unicellular organisms do not breathe in the typical sense, but they respirate by allowing oxygen to enter the cell membrane through the process of diffusion. Because they are so small, they do not have the organs, pores and entryways to breathe like multicellular organisms.Full Answer >
