In most people's minds, the tropical rainforest is a very hot and mysterious place, and it's also a place that tempts people to explore. However, if ecologists were to explain it, it wouldn't be so romantic. The answer is quite rigorous — the tropical rainforest is a biome in tropical regions, mainly distributed in Southeast Asia, Australia, the Amazon River basin in South America, and the Congo River basin in Africa. The tropical rainforest regions have a hot climate all year round with abundant rainfall. The annual rainfall is usually about 2,000 millimeters, and the average monthly temperature throughout the year exceeds 18℃. There are almost no seasonal differences in spring, summer, autumn and winter, making it the area with the most abundant species of plants and animals.
In fact, identifying the tropical rainforest is not difficult at all, because it has four distinctive characteristics, which are also the four wonders that represent the tropical rainforest. In addition to the already mentioned phenomena of tabular roots and old stems flowering, the other two wonders are the phenomenon of aerial gardens and the numerous vines. The so-called "aerial gardens" or "crown gardens" refer to the various epiphytic plants, such as ferns, mosses, algae, and fragrant orchids, that are found on the trunks, branches, and twigs of trees in the rainforest. They grow on the trunks, branches, and twigs of trees, as if covering the trees with a thick green coat. Especially when the orchids are in full bloom, they compete with each other in beauty in the sky. Why can we only see such a wonder in the tropical rainforest? Because the humid and high-temperature environmental conditions there are particularly suitable for the growth of epiphytic plants. Some epiphytic plants are grown and developed after the seeds are carried to the big trees by bird droppings, but another important reason for the creation of the aerial garden landscape is the large number of vines. Vines, which look like long snakes, can be seen everywhere in the tropical rainforest. They climb from one tree to another, from the bottom to the crown, and then hang down from the crown, intertwining and tangling like a huge flowering spider's web in the dense forest.
