A liana is a type of climbing plant that typically grows in tropical rainforests. These long, woody vines use trees and other structures for support as they reach towards sunlight. Lianas can be found in various species, including vines and creepers, and they play a crucial role in the ecosystem by providing habitat and food for many animals. Lianas are important for forest dynamics, as they can affect the growth and health of trees. They often compete with trees for light and nutrients, which can influence the overall structure of the forest. Additionally, lianas contribute to the biodiversity of their habitats, supporting various forms of life.
