Decomposition is rapid and soils are subject to heavy leaching. There they can find all of their necessities and rarely have to come down to the floor of the forest. In addition to the trees, mosses and lichens are very common, often growing as epiphytes. Smaller sized rainforests can be found in Central America, Madagascar, India, Northern Australia and the Pacific Islands. World Distribution: This is a small biome in terms of area covered. The latter is more southerly, lower in elevation, and closer to the ocean, all conditions that conspire to make the Hoh a warmer temperate rainforest than you see at Chilliwack. Tropical Rainforest Biome Characteristics In a tropical rainforest biome, there are several characteristics that have been identified.
Precipitation averages approximately 250 centimeters 100 inches annually. Along with this the fog is beneficial because it provides moisture for plants. Rain forests belong to the tropical wet climate group. This warm and wet area of the planet is teeming with life because sunlight and water is the perfect environment for a wide range of plants and animals. Frogs, lizards, and insects live in that area of water.
However, shallow roots can't support huge rainforest trees, so many tropical trees have developed huge buttress roots. In the water of the tropical rainforest biome you will find various fish. The Understorey is home to many insects and birds. Bracket fungi, above and to the right, are found on standing trees that are dead or in the process of dying. This tree usually occupies the flooded parts of the forest. Trees are distinguished by broad leaves that are lost annually and include such species as oak, hickory, beech, hemlock, maple, basswood, cottonwood, elm, willow, and spring-flowering herbs.
The ground animals have to pass through the dense and thick covers of trees, shrubs and climbers and thus they have acquired special qualities to make their way through the forests viz. Just be sure to stay cool! For example, it extends upto Vera Cruz in Mexico about 19°N and upto 30° S in South America fig. While tropical rainforests around the world have many similarities in their climates and soil composition, each regional rainforest is unique. Colorful and unique animal species are found here. If conditions are right, they fuse to form a multinucleate mass which continues to crawl around eating bacteria.
The road was blocked at this point, so we hiked on around the lake follow the orange dots in the image next to the topo map above to the end of the lake and up the Chilliwack river right. The flowers also offer nectar that hummingbirds, , and butterflies are able to consume. The interception of rainwater by the uppermost forest canopy also allows much evaporation of intercepted rainwater because the rainwater is held at the outer surfaces of the leaves. Bacteria make the smallest organisms living in this biome. It should be noted that timbering can be very difficult here because of steep mountain slopes. Most of the rainfall is received through convectional mechanism which yields heavy downpour through cumulonimbus clouds daily normally between 2p. There were several types of aquatic plants here, including a floating plant below.
Except 2 or 3 months generally every month receives rainfall of at least 200mm. They are able to decompose anything on the forest floor very rapidly. The temperature will not go above 93 degrees and the humidity is always between 77 and 88 percent. Despite relatively consistent rain in these ecosystems, there are distinct dry seasons in some rainforests. The annual precipitation of a rain forest is greater than 150 cm. The trees that are forming the canopy area can reach a height up to 40 meters 130 feet , and their dense crowns are blocking the sunlight from reaching the ground. They occur near the equator, within the area bounded by latitudes 23.
The hot and humid conditions create an ideal environment for the growth of bacteria and other microorganisms. This steady flow of radiation produces consistently high temperatures throughout the year. The canopy also keeps sunlight from reaching the plants in the understory. These creepers are so circuitous and highly irregular in form that it becomes difficult to find out their actual lengths. The driest season comes between June and August with an average rainfall of approximately 6 inches. It is common for them to get at least 100 inches per year. Various types of fruits and nuts grow on the plants and in the trees.
The presence of humans in rainforests can vary. This cycle repeats itself, which is why there is constant rainfall in tropical rainforest biomes.

The temperature in tropical rainforests rarely exceeds 93 — 97 degrees fahrenheit and usually does not drop below 65 — 68 degrees fahrenheit. These herbaceous plants do not form dense cover and have fewer species because the absence of light does not allow much growth of herbaceous plants.
Sloths have also become attractive for certain types of algae to grow on, further camouflaging the sloths and allowing algae to reach nutrients. These belong to the category of vines and range in form from fine string-like stems to massive cable-like forms. It grows on the surface of other plants, usually trees. Some have a thickness that equals the circumference of a human being. The silt, and the nutrients and pollutants it carries, are a threat to nearshore marine organisms as well as freshwater organisms in the river itself, and the area the silt is coming from can't be too pretty either.
