Areas that have more plants have more nutrients. Plants receive and give of nutrients when they die. So areas with little water and plants have little nutrients. Also the sun damages organic matters.
<em>Desert soils are poor in organic matter because there are very less plant remains in the soil.
</em>
<u>Explanation</u>:
<em>A desert has extreme conditions which support less life.</em> Organic matter in soil called humus is formed by the deposition of dead plants and animals in the soil. <em>Soil contains decomposing microbes which act upon the dead plant and animal remains converting them to organic matter.
</em>
In deserts the availability of water is very low which limits the growth of plants there. Animal population is also very less in desert areas. <em>Above all that the extreme heat of the desert destroys the less amount of organic matter formed.

<u>Option-(B):</u> The following is not an observation or inference on which natural selection is based is the characteristics of a poorly adapted individuals which can never produce offspring.
Explanation:
The idea of natural selection basically follows the analyses of the heritable characters which passes from one generation into another, having the specific set of data or genome been transferred into there descendants. And how each specie goes through the process of survival in order to have more chances to acquire the required natural resources and shelter for them selves inside a region or area.
