They cannot get the nitrogen they need from the atmospheric supply. WHat?

Forests provide homes and food sorces for many organisms and is able to suport a diversity of organisms. (Ex. Tropical Rainforest.) And with so many plants the output of oxygen from photosynthesis from every plant in the rainforest also supports human life.
Oxygen is a colourless, odourless, tasteless gaseous chemical element which appears in great abundance on Earth, trapped by the atmosphere. Many people are familiar with oxygen, because it is a vital component of the respiration process; without oxygen, most organisms will die within minutes. A number of forms of oxygen and oxygen compounds can be found in nature. Oxygen can also be isolated and sold in pure form for an assortment of uses, and was first isolated and identified in 1774.

Anaerobic organisms do not require oxygen to survive. On earth, those organisms are limited to many types of bacteria and obligate anaerobes.

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.

Oxygen is being renewed constantly by the process of photosyntesis which absorbs carbon dioxide and converts it into oxygen. The rate of photosyntesis is higher than the amount of respiration, so the amount of organisms will not make oxygen dissapear.
increased oxygen in the atmosphere caused the extinction o many single-celled organisms.
Many things. Titanium burns well in both oxygen and nitrogen.

CHON - the most common are oxygen, hydrogen, carbon, and nitrogen.
