A tropical rain forest is a forest that is located in a region that is warm year round with tall trees. On average, between 50 to 260 inches of rain falls in a tropical rain forest each year.Know More
Almost all rain forests are located near the equator. The average humidity in rain forests is between 77 and 88 percent and the temperature rarely rises above 93 degrees Fahrenheit. Most rain forests have a season where less rain falls, and some have a dry season.
Rain forests cover less than six percent of the earth's land area, but scientists estimate that more than 50 percent of the planet's animals and plants live in tropical rain forests. It is also thought that 40 percent of the earth's oxygen comes from rain forests. These rain forests are also home to more types of trees than any other place on earth. Trees account for 70 percent of all plants within the rain forest.
The trees within rain forests often do not grow branches until about 100 feet in the air. Branches lower on the tree are less likely to receive light, making it more important to grow branches higher up. Trees in rain forests also have bark that is thin and smooth because there is little danger the tree will face freezing temperatures or lose too much water.Learn more about Environmental Science
Some of the abiotic factors found in a tropical rainforest are high temperatures, heavy rainfall, poor nutrient content in soil and sunlight that is found primarily at the tree canopy level while remaining limited at ground level. Because of the heavy overhead canopy, the forest floor may receive as little as 2 percent of the sunlight. Precipitation, which is a significant abiotic factor in a non-aquatic ecosystem, can range between 98 and 177 inches annually in a tropical rainforest.Full Answer >
One of the most interesting facts about the tropical rainforest is that half of the plants and animals on the planet live in these habitats and many species may still be undiscovered. Rainforests contain two-thirds of earth's flowering plant species, and over one-fourth of natural medicines have been discovered there.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 >
Abiotic factors that influence regeneration in a dry tropical rainforest include low soil moisture and high variation in rainfall based on season. Deciduous plants are most likely to regenerate within this generally dry environment.Full Answer >
