why is the plant circumference of camphor bus tree bigger than olive three across a elevation gradient

There could be several reasons why the plant circumference of a camphor tree is bigger than that of an olive tree across an elevation gradient:

1. Growth rate: Camphor trees tend to have a faster growth rate compared to olive trees. This means that they can accumulate more biomass and increase in size more quickly.

2. Adaptability: Camphor trees are more adaptable to different environmental conditions, including elevation gradients. They may have physiological attributes that allow them to thrive in a wider range of elevations compared to olive trees.

3. Soil fertility: The soil at higher elevations may be richer in nutrients and organic matter, providing better conditions for plant growth. Camphor trees might benefit more from these nutrient-rich soils, allowing them to grow more compared to olive trees.

4. Water availability: Elevation gradients can impact water availability, with higher elevations often experiencing more precipitation. Camphor trees may have a higher water requirement than olive trees and are able to take advantage of the increased water availability at higher elevations.

5. Competitive advantage: Camphor trees may have a competitive advantage over olive trees, outcompeting them for resources such as light, water, and nutrients. This advantage could be more pronounced in specific elevation zones.

It is important to note that these factors are generalizations and can vary depending on specific local conditions and species characteristics. Additionally, other environmental factors such as temperature, slope aspect, and human interference can also influence plant growth and size.
