Question

There is scanty vegetation in the desert. give reason

Answer 1

The plains have little flora. A desert is defined by minimal rainfall, sparse flora, and extreme temperatures. These climatic circumstances are not conducive to plant development. This is why plains have so little flora. (ii) Sahara arid dwellers dress in thick garments. The deserts have sparse greenery due to unfavourable climatic circumstances for the flora world to thrive. The desert has either an extreme hot or extreme frigid temperature and gets little rainfall, making it unsuitable for vegetation growth. The Sahara arid people dress in thick garments. The temperature in the deserts is either very hot and arid or very frigid and dry, making it impossible for vegetation to develop. Rainfall is scarce. HenceAs a result, vegetation cannot develop in dry circumstances. For the most part of the year, the soil is either sandy (in hot deserts) or blanketed in snow (in frigid deserts). The flora of an area is typically determined by two factors: temperature and soil. The desert's climatic conditions are either extremely hot and arid or extremely frigid and dry, making it unfit for plant development in this area.

Answer 2

Due to the extreme climate, the desert has very little vegetation. High temperatures, erratic rainfall, and strong winds are all characteristics of deserts, making it challenging for plants to grow and survive.

The most significant constraint on plant growth in the desert is a lack of water. Due to the high temperatures, the little rainfall that does fall is frequently quickly absorbed by the soil or evaporates, leaving plants with little water available. As a result, desert plants have developed deep root systems, small leaves, and the capacity to store water in their tissues, all of which make them highly adapted to water conservation.

The desert's lack of vegetation is also caused by the high temperatures and strong winds. Plants can lose water through evaporation from their leaves at higher temperatures than they can absorb from the soil. By speeding up the rate at which plants lose water through transpiration and evaporation, strong winds can make water loss even worse.

Overall, the desert's low and irregular rainfall, high temperatures, and strong winds make it hard for plants to grow, which is why there isn't much vegetation.
