PHOSPHORUS CYCLE

Question: Phosphorus cycles extremely slowly through ecosystems due to the afct that the major reserviors of this nutrient are contained largely in rock and other substrates. As a consequence, this nutrient often limits primary production Discuss this statement in term sof the global phosphorus cycle, and outline the general patterns of the cycle. What human activities are considered to impact upon the phosphorus cycle? Answer: Introduction In the ecosystems, nutrients continuously cycle through living-organisms and …showed first 75 words of 1452 total…

The inadequate nutrient supply limits the primary production as well as negatively affects the growth of plants and animals. However, the excess input of phosphorus and other nutrients to ecosystems with fertilisers causes nutrient enrichment problem, which destroys many valuable species and contaminates the water quality for drinking and other uses. Recognising these problems may help people to use natural resources more effectively.
