Final answer:
The ecosystems present in Arabia are predominantly Desert and Oasis Ecosystems, which play a significant role in determining water availability, settlement patterns, and influencing traditional lifestyles such as nomadic living and oasis farming.
Step-by-step explanation:
The ecosystems present in Arabia predominantly fall under the category of Desert and Oasis Ecosystems. These ecosystems vary greatly within themselves. For instance, the desert in Saguaro National Park, Arizona, is known for its abundance of plant life in comparison to the stark, rocky deserts found in places such as Boa Vista island off the coast of Western Africa. In Arabia, the desert ecosystem is characterized by extreme heat, scarce water, and sparse vegetation, which influences water availability and dictates settlement patterns. Oasis ecosystems, as pockets of fertility, become focal points for human habitation and agriculture in such arid regions.
Due to the harsh living conditions in the desert, access to water through oases dictates where people can settle and live. As a result, human activities such as agriculture and settlement development are heavily centered around these water-rich areas, shaping the society and economy of the regional population. Over time, the desert ecosystem has influenced traditional patterns of nomadic lifestyle, camel herding, and oasis farming, which are integral parts of Arabian culture.
