Analysis

Equatorial forests, also known as tropical rainforests, are characterized by dense vegetation and extremely high biodiversity. Trees grow closely together forming a continuous canopy. These forests support enormous species diversity due to year-round heat and rainfall. Epiphytes such as orchids and ferns commonly grow on tree branches for physical support. Therefore, all three statements are correct.
