Tropical rainforest is characterized by

A biome is a large area characterized by its vegetation, soil, climate, and wildlife. There are five major types of biomes: aquatic, grassland, forest, desert, and tundra, though some of these biomes can be further divided into more specific categories, such as freshwater, marine, savanna, tropical rainforest, temperate rainforest, and taiga. Aquatic biomes include both freshwater and marine biomes. Freshwater biomes are bodies of water surrounded by land—such as ponds, rivers, and lakes—that have a salt content of less than one percent. Marine biomes cover close to three-quarters of Earth’s surface. Marine biomes include the ocean, coral reefs, and estuaries. Grasslands are open regions that are dominated by grass and have a warm, dry climate. There are two types of grasslands: tropicalgrasslands (sometimes called savannas) and temperategrasslands. Savannas are found closer to the equator and can have a few scattered trees. They cover almost half of the continent of Africa, as well as areas of Australia, India, and South America. Temperategrasslands are found further away from the equator, in South Africa, Hungary, Argentina, Uruguay, North America, and Russia. They do not have any trees or shrubs, and receive less precipitation than savannas. Prairies and steppes are two types of temperategrasslands; prairies are characterized as having taller grasses, while steppes have shorter grasses. Forests are dominated by trees, and cover about one-third of the Earth. Forests cont...

Part I: THE RAINFOREST CANOPY An estimated 50-90 percent of life in the rainforest exists in the trees, above the shaded forest floor. Primary tropical rainforest is vertically divided into at least five layers: the overstory, the canopy, the understory, the shrub layer, and the forest floor. Each layer has its own unique plant and animal species interacting with the ecosystem around them. The overstory refers to the crowns of emergent trees which soar 20-100 feet above the rest of the canopy. The canopy is the dense ceiling of closely spaced trees and their branches, while the understory is the term for more widely spaced, smaller tree species and juvenile individuals that form a broken layer below the canopy. The shrub layer is characterized by shrubby species and juvenile trees that grow only 5-20 feet off the forest floor. The forest floor is the ground layer of the forest made up of the trunks of trees, fungus, and low-growing vegetation. These layers are not always distinct and can vary from forest to forest, but serve as a good model of the vegetative and mechanical structures of the forest. Costa Rican rainforest The overstory is characterized by scattered emergent trees that tower above the rest of the canopy, the tops of some species exceeding 210 feet (65 m). Below the overstory trees, the canopy stretches for vast distances, seemingly unbroken when observed from an airplane. However, despite overlapping tree branches, canopy trees rarely interlock or even touch...

-Tropical Rainforest Definition: 5 Ways to Define the Tropical Rainforest Ecosystem -Unique Characteristics of Tropical Rainforest Ecosystem -Conclusion Tropical Rainforest Definition: 5 Ways to Define the Tropical Rainforest Ecosystem Multiple criteria can be used to define the tropical rainforest, because of the dynamic and ecologically-robust nature of this ecosystem. One of such criteria is the climate of tropical rainforest , which differentiated it among other terrestrial biomes. The tropical rainforest definition below highlights basic attributes of its climate; Tropical rainforest is a terrestrial biome that is generally located close to the equator, and has distinctive climatic conditions, such as abundant rainfall, solar radiation, high-relative humidity, and warm temperatures. One of the outcomes of tropical climatic conditions is high species-richness and diversity. This can be analyzed by observing trends in the abundance and distribution of organic populations of animals and plants in the tropical rainforest . Below is an alternative tropical rainforest definition that lists some categories of tropical forest plants; Tropical rainforest is a highly-diverse ecosystem, characterized by rapid-growing vegetation which includes various species of trees, shrubs, herbaceous plants, ferns, grasses, climbing plants like vines and lianas, epiphytes, non-vascular ground-covers like mosses and lichens. Tropical Rainforest Definition: Vines, Lianas and Epiphytes are all C...

× Temperate forestBiomes are large geographic areas that contain distinctive plant and animal communities. Biomes may be composed of multiple ecosystems, and the primary factors which distinguish different biomes are temperature and precipitation. A biome's temperature and precipitation regime influence soil temperature and soil moisture conditions, as well as the soil type, and are responsible for the presence of distinctive vegetation types in each biome. Major biome types include forests, grasslands, tundra, deserts, shrublands, and wetlands. Educator Background Overview Biomes are large geographic areas that contain distinctive plant and animal communities.

The correct answer is Maximum biodiversity. Key Points • The tropical rain forest is a forest with tall trees in a region of year-round high temperatures where an average of 50 to 260 inches of rain falls yearly. • Tropical rainforests are areas of extremely high biodiversity compared to other ecosystems. • In the tropical rainforests of Borneo, scientists have documented more than 15,000 plant species, including 2,500 species of orchids. • Biologists estimate that tropical rainforests contain about 50% of the world’s terrestrial plant and animal species, yet they encompass only about 6% of the world’s land area. Important Points • Rain forests belong to the tropical wet climate group. • The temperature in a rain forest rarely gets higher than 34 °C or drops below 20 °C, average humidity is between 77 and 88%. • There is usually a brief season of less rain. • Almost all rain forests lie near the equator. • Rainforests now cover less than 6% of Earth’s land surface.

Rivers, streams, and creeks in the rainforest Tropical rainforests have some of the largest rivers in the world, like the Amazon, Madeira, Mekong, Negro, Orinoco, and Congo (Zaire), because of the tremendous amount of precipitation their watersheds receive. These mega-rivers are fed by countless smaller tributaries, streams, and creeks. For example, the Amazon alone has some 1,100 tributaries, 17 of which are over 1,000 miles long. Although large tropical rivers are fairly uniform in appearance and water composition, their tributaries vary greatly. Many tropical rivers and streams have extreme high and low water levels that occur at different parts of the year. In addition to rivers, rainforests have conventional, free-standing lakes and so-called oxbow lakes, formed when a river changes course. These lakes are home to species adapted to the quiet, stagnant conditions. Tropical waters, whether they be giant rivers, streams, or oxbow lakes, are almost as rich in animal species as the rainforests that surround them. But they, too, are increasingly threatened by human activities, including pollution, siltation resulting from deforestation, hydroelectric projects, and over-harvesting of resident species.

This article discusses the tropical rainforest climate based on its major elements, as follows; 1). Precipitation in the Tropical Rainforest (as one of the Characteristics of Tropical Rainforest Climate) One of the core attributes of tropical rainforest climate is high amounts of precipitation, all year-round. In fact, high precipitation is such a prominent characteristic of the rainforest that it is featured in the name of this ecosystem , which describes a forest with abundant rain . Annual rainfall in the tropical rainforest ranges from 1,800 to 10,000 millimeters on average [ As a result of the intensity and consistency of rainfall in tropical rainforests, there is no intense dry season or distinct tendency of dryness. The only variations are in the monthly intensity of rainfall, and these are minor compared to seasonal weather changes in other ecosystems. Factors influencing the climate of tropical rainforests in terms of precipitation include; topography and inter-tropical convergence. The Inter-Tropical Convergence Zone (ITCZ) is close to the equator and serves as a meeting-point for northern and southern trade winds [ Rainfall is crucial to the efforts at identifying and distinguishing seasons in the tropical rainforest. Seasons in a tropical rainforest are; wet and dry seasons respectively, each of which is believed to last for approximately six months. As earlier stated; the dry season is not prominent, or even very distinctive, in a tropical rainforest. The peri...
