Commensalism
Because, to reach the sunlight, orchids get a boost from the forest trees. Orchids will attach themselves and grow on the trunks of the trees. In this way, the orchids move up off the dark forest floor and closer to the sunny canopy
An example of commensalism in the Australian outback is the relationship between certain epiphytic plants, like orchids or ferns, and eucalyptus trees. The orchids grow on the branches of the trees, benefiting from the elevated position for sunlight and moisture without harming the host tree. The eucalyptus tree is neither helped nor harmed by the presence of the orchids, making this a clear case of commensalism.
Terrestrial orchids are orchids that live in the soil of the ground and not in trees
Commenalism
Trees provide orchids with a habitat to grow on, as orchids are epiphytic plants that do not root in soil. The trees do not receive any direct benefits from the orchids, but the presence of orchids can enhance the overall biodiversity and ecosystem health of the habitat.

A mutualistic relationship between the mycorrhizae and the roots of the trees.
The relationship between orchids and trees, known as epiphytism, offers advantages such as increased access to sunlight and reduced competition for ground resources, allowing orchids to thrive in diverse environments. However, disadvantages include vulnerability to environmental changes and potential reliance on the host tree for moisture and nutrients. If the host tree suffers from disease or stress, the orchid may also be adversely affected. Additionally, this relationship can become parasitic if the orchid significantly harms the tree's health.
Not all Orchids need to grow on trees, only the epiphytes, terrestiall Orchids grow in the soil.
