Why would an olive tree be best adapted to grow in an arid area compared to a camphor bush tree
Olive trees are better adapted to grow in arid areas compared to camphor bush trees due to several reasons:
1. Drought tolerance: Olive trees have a greater ability to withstand long periods of drought, as they have evolved to survive in Mediterranean climates with hot, dry summers. They have developed deep root systems that can access water sources deep underground.
2. Water conservation: Olive trees have smaller and more waxy leaves, which helps reduce water loss through transpiration. This adaptation allows them to conserve water during dry periods.
3. Salt tolerance: Olive trees can also tolerate higher levels of salinity in the soil, which is common in arid areas where irrigation water may contain salt. They have mechanisms to filter out excess salt and prevent damage to the roots.
4. Adaptability to poor soil conditions: Olive trees can grow well in poor, rocky soils, which are often found in arid regions. They can extract nutrients from the soil more efficiently compared to many other tree species.
On the other hand, camphor bush trees may not be as well-suited to arid areas because they have not evolved specific adaptations to withstand prolonged periods of drought or high salinity levels in the soil. They are more commonly found in temperate or subtropical regions with higher rainfall and more moisture availability.
