This Melon Builds a Whole Ecosystem in the Desert

The Namib Desert, one of the oldest and driest deserts, hosts unique flora and fauna with remarkable adaptations. The Nara melon, a key species, thrives by creating sand mounds called hummocks, capturing moisture, and supporting a diverse ecosystem. Its deep roots access groundwater, and it may harvest fog moisture. The plant's adaptations allow it to survive extreme aridity, providing resources for various species and local communities. Despite its resilience, the Nara melon cannot be cultivated outside its niche environment, remaining a unique element of the Namib Desert.

What makes the Namib Desert one of the most extreme environments on Earth?

• It has a high annual rainfall.

• It is covered in dense forests.

• It is located near the equator.

• It has been hyper-arid for millions of years.

How does the Nara plant create a stable habitat in the desert?

• By growing tall trees.

• By building sand mounds called hummocks.

• By spreading its seeds through animals.

• By absorbing sunlight through large leaves.

What unique feature allows the Nara plant to access water in the desert?

• Its large, flat leaves that capture rain.

• Its capacity to photosynthesize at night.

• Its roots that extend up to 50 meters below the sand.

• Its ability to store water in its leaves.

In what way does the Nara plant contribute to the desert ecosystem?

• By attracting tourists to the region.

• By preventing sandstorms.

• By producing large quantities of oxygen.

• By providing shade and nutrients to other species.

Why can't the Nara melon be cultivated outside its natural habitat?

• It has adaptations that are too specific to its natural environment.

• It can only grow in high-altitude regions.

• It needs a constant supply of rainwater.

• It requires a specific type of soil found only in the Namib Desert.
