我想知道熱帶雨林的動植物和特徵!!!!!!!!!20點

Bromeliads
Bromeliads are related to the pineapple family. Their thick, waxy leaves form a bowl shape in the centre for catching rainwater. Some bromeliads can hold several gallons of water and are miniature ecosystems in themselves providing homes for several creatures including frogs and their tadpoles, salamanders, snails, beetles and mosquito larvae.

Epiphytes
Epiphytes, or air plants, grow everywhere but can be found mainly on the branches, trunks, and even the leaves of trees. The name 'epiphyte' comes from the Greek word 'epi' meaning 'upon' and 'phyton' meaning 'plant'.

Lianas
Ninety per cent of the world's vine species grow in tropical rainforests. Lianas are a type of climbing vine found throughout tropical rainforests. They have thick, woody stems and come in various lengths (up to 3,000 ft) and varying shapes. They begin life on the forest floor but depend on trees for support as they climb upwards towards the sunlight they need for survival.

Orchids
Orchids comprise one of the most abundant and varied of flowering plant families. There are over 20,000 known species and orchids are especially common in moist tropical regions.

Saprophytes
Saprophytes are the organisms that act as the rainforests decomposers, competing with the heavy rainfall which constantly washes away nutrients on the forest floors.

Carniverous Plants
Some plants are adapted to obtain nutrients from animal matter. The best known of these is probably the Venus fly trap, but more impressive is the pitcher plant Nepenthes rafflesiana, found in southeast Asia. This plant grows to 30 feet tall and may have pitchers 12 inches in length, usually crammed full of digested insects.
