The layered structure of a tropical rainforest includes the forest floor, understory, canopy and emergent layer. Each layer contains different flora and fauna unique to its environment. The fundamental difference between these layers is the amount of sunlight they receive. According to the BBC, the upper layers are bathed in sunlight, but the forest floor is almost completely dark.Know More
The rainforest floor has scant vegetation because it is an extremely dark environment. This attracts certain large land mammals that cannot fly, burrow or climb trees. Human cultures that live in the rainforest also dwell on the forest floor.
The BBC explains that the second layer of a rainforest is the understory, a shady zone packed with shade-loving trees, shrubs and vines. Its denizens include hundreds of bird species, insects, snakes, arachnids and rodents. Larger animals such as leopards also live in the understory.
The canopy layer receives much more sunlight than the understory and the forest floor. Some of its plants have roots in the understory. The canopy is extremely dense and only permits a small portion of the sunlight to pass into the bottom layers of the rainforest.
The emergent layer vaults above the canopy and contains the tallest trees in the rainforest. The animals living in it include large birds and tiny rodents.Learn more about Environmental Science
Many different factors affect the time it takes for wood to rot, but spruce trees that die and fall to the forest floor usually disappear within 50 to 100 years. Pine logs on the forest floor remain there for 200 to 300 years.Full Answer >
Biotic factors of tropical rainforests around the world include many types of insects, plants and animals, including ferns, mosses, tree frogs and exotic birds. Rainforests on the Earth's surface come in many types, including cloud forests, dry forests and temperate forests, although tropical rainforests comprise the majority of rainforests and contain the largest amount of biodiversity. Tropical rainforests serve as home to over half of all living species, making them ripe with biotic factors.Full Answer >
Since most rainforests are located near the equator, their climate is always hot, wet and humid. Temperatures in tropical rainforests do not change much. The Amazon rainforest generally retains a temperature between 68 to 93 degrees Fahrenheit. It also receives about six to 12 feet of rain every year. Unlike tropical rainforests, temperate rainforests can be found in temperate zones and receive a high amount of rainfall.Full Answer >
The rainforest's tallest trees are kapok trees, which are also referred to as ceiba trees. A kapok tree can reach up to 200 feet in height, towering over other trees. This layer of trees is referred to as the rainforest's emergent layer.Full Answer >
