Tropical Rainforest

Tropical Rain Forest Biome

Rain forests belong to the tropical wet climate group. The temperature in a rain forest rarely gets higher than 93 °F (34 °C) or drops below 68 °F (20 °C); average humidity is between 77 and 88%; rainfall is often more than 100 inches a year. There is usually a brief season of less rain. In monsoonal areas, there is a real dry season. Almost all rain forests lie near the equator.


Plants have adaptations to help them survive (live and grow) in different areas. Adaptations are special features that allow a plant or animal to live in a particular place or habitat. These adaptations might make it very difficult for the plant to survive in a different place. This explains why certain plants are found in one area, but not in another. For example, you wouldn't see a cactus living in the Arctic. Nor would you see lots of really tall trees living in grasslands.



Meteorological Elements

Weather Patterns

In a tropical rainforests rain falls nearly every day. On average about 2500 millimetres of rain falls annually. This, along with the constant temperature hanging around 25-30 degrees Celsius, makes the rainforest an extremely humid place. Tropical rain forests receive almost 12 hours of sunlight every day. Since a lot of sunlight emanates into the rainforest, a large amount of energy is stored by plants and then later eaten by animals, creating a more lively and thriving ecosystem for both plants and animals in this biome.

Geographic Features

A tropical rainforest consists mainly of moss and other lush plantation, rocks, trees, healthy soil, and grasses. The actual land of a rainforest is usually quite rocky, as it isn't uncommon for a rainforest to cover hills and small mountains. Even though there is a lack of light that reaches the forest floor, countless species of plants, animals, and insects continue to thrive in this biome.

Impact on Tropical Rainforest

As human population grows the need for agriculture, energy and development space increases with it. Tropical rainforests cover a massive amount of the world’s tree surface, each year over 90,000 square miles of the forests are harvested for human use. This deforestation has worried environmentalists because of the release of carbon from the machinery and the vegetation. It is believed that deforestation may accelerate the effects of global warming and transform the rainforest climate. Tropical Rainforests harbor 50% of world’s biodiversity, the massive deforestation of the forest has caused the total land mass to go 15 million km squared to about 8 million km squared, this is nearly half; it is estimated that nearly 2% of the rainforest is lost annually. Furthermore, Approximately 137 species are lost in this biome per day, including both species of plants and animals and insects.
