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 >

Chemoautotrophs obtain energy by using oxygen or compounds with high oxygen content to oxidize, or take electrons from, sulfur compounds, hydrogen, elemental sulfur, ammonia or metals. They use some of the energy obtained from these oxidation reactions to create organic compounds from reactions with carbon dioxide.Full Answer >
Fungi are aerobic organisms; they must have free oxygen to survive. They cannot create their own food using the sun like a plant does. Fungi must get their energy from living off of dead plants and other fungi.Full Answer >
