Answer:
The Namib Desert is one of the driest places on Earth, receiving less than 10 millimeters of rainfall per year on average. This extreme aridity is one of the primary reasons why plant growth is limited in the desert.
Plants require water to survive and grow, and the Namib Desert's lack of rainfall makes it difficult for plants to obtain the water they need. Some plants in the Namib Desert have adapted to survive in this harsh environment by developing specialized mechanisms to absorb and store moisture, such as deep tap roots or succulent leaves. However, even these plants have limited growth and reproduction due to the lack of water.
In addition to the lack of water, the Namib Desert has nutrient-poor soils with high salt content, which also makes it difficult for plants to grow. The combination of these factors creates a challenging environment for plant growth in the Namib Desert.
Despite the harsh conditions, the Namib Desert is home to a variety of unique and specialized plant and animal species that have adapted to survive in this extreme environment.
