Rainforests are home to half of all the living animal and plant species on the planet. [7] Two-thirds of all flowering plants can be found in rainforests. [5] A single hectare of rainforest may contain 42,000 different species of insect, up to 807 trees of 313 species and 1,500 species of higher plants. [5]
Fungi are also very common in rainforest areas as they can feed on the decomposing remains of plants and animals. The great diversity in rainforest species is in large part the result of diverse and numerous physical refuges , [ 25 ] i.e. places in which plants are inaccessible to many herbivores, or in which animals can hide from predators.
The fifth and final layer is the herb layer which is the forest floor. The forest floor is mainly bare except for various plants, mosses, Lycopods and ferns. The forest floor is much more dense than above because of little sunlight and air movement. [2] Plant species native to the tropics found in tropical ecosystems are
The biodiversity of plant species is the highest on Earth with one 2001 study finding a quarter square kilometer (62 acres) of Ecuadorian rainforest supports more than 1,100 tree species. [54] A study in 1999 found one square kilometer (247 acres) of Amazon rainforest can contain about 90,790 tonnes of living plants.
This is a list of plants found in the wild in Amazon Rainforest vegetation of Brazil. The estimates from useful plants suggested that there are 800 plant species of economic or social value in this forest, according to Giacometti (1990). [1]
The emergent layer, above the canopy, exists in tropical rainforests. Each layer has a different set of plants and animals, depending upon the availability of sunlight, moisture, and food. The Forest floor is covered in dead plant material such as fallen leaves and decomposing logs, which detritivores break down into new soil. The layer of ...
Lovejoy and other WWF biologists, and Brian Boom, the director of the NY Botanical Garden, facilitated her travel to Manaus, Brazil, to experience the rainforest firsthand. She explored the vast forest around Lovejoy's research site, part of his famous "forest fragments" project, and sketched and photographed the plants and animals there. [2]
Trees from the plant families Burseraceae and Sapotaceae are also common in the canopy. [1] There is an understorey stratum under the canopy, composed of shade-tolerant trees draped with lianas and epiphytic orchids and ferns. Understorey trees are commonly of the plant families Euphorbiaceae, Rubiaceae, Annonaceae, Lauraceae, and Myristicaceae.
