What are the advantages when a plant grows on a tree branch?

When a plant grows on a tree branch, it benefits from increased access to sunlight, which is crucial for photosynthesis. This elevated position often provides a more favorable microclimate, with better airflow and reduced competition for resources from ground-level plants. Additionally, these plants can utilize the tree for support, allowing them to reach optimal heights without expending energy on developing extensive root systems. This relationship can also enhance nutrient uptake from the tree's organic matter, benefiting both the plant and the host tree.
