Various animal species stay in environments characterised via a seasonal relief within the availability of water, which regularly yet now not continuously happens whilst temperatures are maximum. for plenty of such animals, survival in the course of the hardest season calls for spending lengthy classes of time in a slightly inactive nation referred to as aestivation.
Nitrogen and sulfur compounds are consistently synthetized, degraded and switched over into other kinds in nature. there are numerous similarities within the precept difficulties and uncomplicated mechanisms of the biology of inorganic nitrogen and sulfur. Many info usually are not but understood and therefore are the topic of lively research across the world.
