Although 78 percent of our atmosphere is comprised of nitrogen gas, usable nitrogen is a limited commodity. Most organisms can tap the element for growth and function only when, through a process called nitrogen fixation, it has been converted into ammonia or nitrates. Nitrogen Fixation Geo-grafik...
(1999). How do soil organisms affect total organic nitrogen storage and substrate nitrogen to carbon ratio in soils? A theoretical analysis. Oikos, 86(3), 430 to 442.Zheng DW, Ågren GI, Bengtsson J (1999) How do soil organisms affect total organic nitrogen storage in soils and substrate...
Some protection from radiation, such as being on a rock, seems to help organisms survive the journey. But wherever they land, these space travelers need an environment that will allow them to live and grow. So with these ideas in mind, is it fair to say that we humans might be aliens?
Why are nutrients important to living organisms? Why do dogs eat paper? What happens when a bug's exoskeleton breaks? Why do animals live in forest habitats? Why do cats eat their own vomit? Why do herbivores need nitrogen? Why are plants autotrophs?
Why is water so important to living organisms? Why does the body need fat? Why do we need scientific ethology? Why is water so important for life? Why are all living things on Earth carbon-based? Why, chemically, is nitrogen not more available to living things?
Aquatic organisms need DO to survive, so that's why some water bodies have artificial aeration. Examples include a paddle wheel or a fountain in the middle of a pond, the use of an air stone in an aquarium, and pumping air into aeration basins at wastewater treatment plants to sustain mic...

Understanding how chemicals interact with each other and how living organisms live is also an important aspect of modern day chemistry. The sheer number of possible chemical names is mind boggling. Not all compounds can be recognized by the human eye, making chemical identification a daunting task...
(carbon containing) waste and break it down into its simplest parts. This produces a fiber-rich, carbon-containinghumuswith inorganic nutrients like nitrogen, phosphorus and potassium. The microorganisms break the material down throughaerobic respiration. All that really means is they need oxygen. ...
Why do living organisms need nutrients? Why do seasons change? Why are humans at the top of the food chain? Why do dogs sleep between your legs? Why do dogs twitch in their sleep? Why did animals evolve to breathe air? Why are humans and other living things not crushed by the pressure...
