Explanation:
Equatorial forests, also known as tropical rainforests, exhibit several unique characteristics:
Presence of tall, closely set trees with crowns forming a continuous canopy: Equatorial forests are known for their dense vegetation, characterized by tall trees that grow close together. The crowns of these trees interlock, creating a dense canopy that shades the forest floor and blocks sunlight from reaching the lower layers.
Coexistence of a large number of species: Equatorial forests are incredibly diverse in terms of species richness. They support a wide variety of plants, animals, and microorganisms. The coexistence of numerous species within a relatively small area is a distinctive feature of equatorial forests.
Presence of numerous varieties of epiphytes: Epiphytes are plants that grow on other plants for support, but they do not rely on the host plant for nutrients. Equatorial forests are known for their abundance of epiphytes, including various types of mosses, ferns, orchids, and bromeliads. These plants grow on tree branches and trunks, taking advantage of the high moisture and abundant sunlight in the forest canopy.
