The correct answer to the question is:
- ○ desert
In the African landscape, approximately one-third is characterized as a desert environment. This includes famous deserts like the Sahara Desert in the north of Africa and the Kalahari Desert in the southern part of the continent. These deserts have unique ecosystems adapted to arid conditions, with sparse vegetation and specific animal species that have evolved to survive in harsh desert environments.
Deserts cover vast expanses of land in Africa, playing a significant role in shaping the continent's geography and climate. The lack of rainfall in these regions contributes to the arid conditions and distinctive landscapes found in African deserts.
