Answer:
A. The temperatures are too high.
Explanation:
A desert is a region with extremes of temperatures and little to no rainfall.
Organic matter are the remains of organisms that have died. They are a very important component of soils.
Where temperatures are very extreme, there would be little to no life. Only special organisms that have evolved to adapt will survive such region.
Due to the low amount of plant and animal lives owing from the high temperature of deserts, little to no organic matter forms.
Image result for Is work done when you carry a book across the room at a constant velocity
Work is not done when you carry an object forward. You may have learnt that carrying an object and moving horizontally at a constant velocity has no work done. The truth is, there is a slight amount of work done due to overcoming air resistance in the horizontal direction.
<span>The biome is characterized by climate, temperature, and rainfall. The climatic factors that intervene are the altitude, latitude, and types of soil. Latitude determines temperature and seasonality and defines polar, subpolar, temperate, subtropical and tropical climates. Precipitation and latitude determine wet, sub-humid, dry or seasonal, semi-arid and arid types. The altitude determines the basal, premontane, montane, alpine and snow types. And only soil types are a determining factor in the influence of climatic factors and their variation and behavior within the biome.</span>
