Deserts have little rainfall. However, if the desert is irrigated, it can be, and is, quite porductive.
The lowest net primary productivity usually occurs in extreme environments such as deserts, polar regions, and deep ocean gyres where there is limited access to sunlight, water, and nutrients for photosynthesis. These areas have low plant growth and biomass production, resulting in low net primary productivity.
In deserts, high temperatures can lead to evaporation of water faster than it can be replenished, limiting water availability for plants. Soil composition in deserts is typically poor in nutrients and organic matter, making it challenging for plants to grow. Additionally, low annual precipitation levels in deserts reduce the amount of water available for plant growth, further limiting productivity.
No, deserts or parts of deserts can be several thousand feet in elevation.
No. Height varies widely. There is even a formal division between high deserts (above 2,000 ft) and low deserts.
Low productivity in a company is caused by a number of factors. Poor management, employee dissatisfaction, outdated systems and personal problems of employees all contribute to low productivity.
Clouds do not precipitate in deserts primarily due to low humidity. Deserts have very dry air with low moisture content, which limits the formation of rain clouds. The low humidity prevents sufficient condensation of water vapor in the atmosphere to form clouds that can produce precipitation.
Your question is redundant. All deserts are classified as deserts because of the low precipitation.
There are both cold deserts as well as hot deserts.
Some deserts have low elevation, some have a rather high elevation. Not all deserts have a low altitude.

The only thing all deserts have in common is low rainfall.
