Question

how are forests and deserts related?
forests prevent desertification.
forests are usually found on the outskirts of deserts.
forests and deserts have similar ecosystems.
forests and deserts both help oxygenate our atmosphere.

Explanation:

• Option 1: Forests have root systems that hold soil, retain moisture, and maintain ecological balance, which helps prevent the spread of deserts (desertification).
• Option 2: Forests require more water and different soil conditions than desert outskirts typically provide, so this is incorrect.
• Option 3: Forest ecosystems are rich in biodiversity and depend on moisture, while desert ecosystems are arid and have adapted species; they are not similar.
• Option 4: Forests produce oxygen via photosynthesis, but deserts (with sparse vegetation) do not significantly contribute to oxygenation.

Answer:

A. Forests prevent desertification.
