Thorny bushes are the correct answer for the vegetation found in dry deserts located in the western margins of the continents. Let's delve into the reasons why thorny bushes are the most suitable option:
Scarcity of Rainfall:
- Dry deserts are characterized by extremely low levels of rainfall. As a result, the vegetation in these areas must be adapted to survive with minimal water resources.
- Thorny bushes have evolved to thrive in arid conditions by having long roots that can reach deep into the ground to access underground water sources. They are also able to conserve water by reducing the surface area of their leaves, preventing excessive water loss through transpiration.
Scorching Heat:
- Dry deserts experience high temperatures due to their location in areas with intense solar radiation and minimal cloud cover.
- Thorny bushes have adapted to these extreme heat conditions by having small, narrow leaves that minimize exposure to the sun. This reduces water loss through evaporation and helps the plant conserve moisture.
- Additionally, some thorny bushes have a waxy coating on their leaves, which further helps to prevent water loss and protect against the harsh desert sun.
Vegetation Cover:
- The vegetation cover in dry deserts is generally sparse due to the unfavorable climatic conditions.
- Thorny bushes are well-suited to these environments because they can survive with limited resources and are able to grow in areas where other plants struggle.
- Their thorny nature also serves as a defense mechanism against herbivores, helping to reduce grazing pressure and allowing them to persist in these harsh conditions.
Conclusion:
Considering the scarcity of rainfall, scorching heat, and sparse vegetation cover, thorny bushes are the most suitable vegetation for dry deserts located in the western margins of the continents. Their ability to adapt to arid conditions, conserve water, and withstand high temperatures makes them well-suited for survival in these extreme environments.
