A tree trunk can be ground or you can grind it.
The lower part of the tree which come from the ground is the trunk or bole. Below the soil surface are the roots.
The part of the tree trunk that goes into the ground is called the "root." Roots anchor the tree and absorb water and nutrients from the soil. They also store energy and help support the tree's overall stability and health.

A tree with multiple trunks, also known as a multi-trunk tree, has several main stems growing from the ground. This type of tree differs from a tree with a single trunk, which has only one main stem. Multi-trunk trees often have a more bushy or spreading appearance, while single-trunk trees typically have a more upright and singular shape.
Not by definition. The trunk is considered to be the above ground stem portion of the tree, although depending on the species of tree a certain portion of the trunk extends under the surface before branching out into the root system.
The quickest way for an ant to go from the ground to the tree trunk is to climb directly up the trunk itself. Ants are skilled climbers, using their legs to grasp onto the bark's texture for traction. They can also navigate around obstacles on the ground efficiently before reaching the base of the tree. This direct ascent minimizes the distance traveled and time taken.
