Describe how nutrients
are cycled through desert?

Here ig !

Explanation:

Nutrient cycling in arid ecosystems is described in relation to the influence of precipitation, structural and temporal variability (including nutrient accumulation, intra-seasonal variation, distribution of minerals between ecosystem components and a comparison of turnover rates with other ecosystems) and particular problems of specific minerals (N and P in deficit and Na, Cl, B and Se in excess). Water remains the dominant factor in these arid ecosystems; however, plants cannot fully capitalize on soil moisture unless nutrients are available and vice versa.  The Efficiency of water utilization declines under nutrient stress.
