why is the circumference of a camphor bush tree bigger than an olive tree and the same habitat

The circumference of a tree is primarily determined by its species, age, and overall growth rate. However, when comparing two different species growing in the same habitat, several factors may contribute to the difference in circumference between a camphor bush tree and an olive tree:

1. Genetics: Each species has its own genetic blueprint that dictates its growth potential. Some species naturally tend to grow larger and have thicker trunks, resulting in a greater circumference.

2. Growth rate: Different tree species have varying growth rates, meaning they accumulate wood and increase in size at different speeds. If the camphor bush tree has a faster growth rate than the olive tree, it will eventually surpass it in circumference.

3. Age: Older trees generally have larger circumferences because they've had more time to grow and accumulate wood. If the camphor bush tree is older than the olive tree, it will likely have a larger circumference.

4. Environmental conditions: The habitat in which the trees are growing can have an impact on their growth. Factors like soil quality, availability of nutrients, water availability, and sunlight exposure can influence a tree's growth and, consequently, its circumference.

Considering these factors, it's possible that the camphor bush tree simply has a genetic predisposition for larger growth, a faster growth rate, an older age, or more favorable environmental conditions compared to the olive tree in the shared habitat.
