Answer:
Animal life in the tropical rainforest
Rainforests are tremendously rich in animal life. Rainforests are populated with insects (like butterflies and beetles), arachnids (like spiders and ticks), worms, reptiles (like snakes and lizards), amphibians (like frogs and toads), birds (like parrots and toucans) and mammals (like sloths and jaguars).

Answer:
Biome is another name for a distinct type of ecosystem. Biomes are characterized by their climate, which determines the particular plants found there. The climate and the plants in a biome determine what animals live there. This article addresses the climate and biodiversity of one of Earth’s most diverse and iconic biomes: the tropical rainforest.
The tropical rainforest biome has four main characteristics: very high annual rainfall, high average temperatures, nutrient-poor soil, and high levels of biodiversity (species richness).
Rainfall: The word “rainforest” implies that these are the some of the world’s wettest ecosystems. Rainforests generally receive very high rainfall each year, although the exact amount varies among different years and different rainforests. For example, South America’s tropical rainforests receive between 200 and 300 centimeters (80 and 120 inches, or 6.5 to 10 feet!) of rain in a typical year. Despite relatively consistent rain in these ecosystems, there are distinct dry seasons in some rainforests. Wet and dry seasons of tropical rainforests vary in their timing, duration and severity around the globe. Tropical rainforests also have high humidity; about 88% during the wet season and approximately 77% in the dry season.
Temperature: Tropical rainforests are found near the equator, between the Tropic of Cancer (23°27’N) and the Tropic of Capricorn (23°27’S). The equator receives direct sunlight. This steady flow of radiation produces consistently high temperatures throughout the year. A typical daytime temperature any time of year in tropical rainforests is 29°C (85°F), although temperatures can be much higher. In the majority of tropical rainforests, there is only a 5°C (9°F) difference in temperature between the seasons.
Soil Composition: Since there is a tremendous amount and diversity of foliage in tropical rainforests, you might assume that rainforest soils are rich in nutrients. In fact, rainforest soils are nutrient-poor because nutrients are not stored in them for very long. The heavy rains that occur in rainforests wash organic material from the soil. Although decomposition occurs rapidly in the hot, moist conditions, many of the dead, fallen leaves and other organic detritus are swept away before releasing all of their nutrients. In addition, rainwater seeps into the ground and leaches away nutrients. Nevertheless, the high diversity of decomposers, such as bacteria and fungi accelerates the decomposition process enough that the nutrients released by decomposition are taken up quickly by the plants, instead of being stored in the soil.
Biodiversity: Tropical rainforests are areas of extremely high biodiversity compared to other ecosystems. In the topical 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.
While tropical rainforests around the world have many similarities in their climates and soil composition, each regional rainforest is unique. You will not find precisely the same species living in all the tropical rainforests around the world. For example, the species in African tropical rainforests are not the same as the species living in the tropical rainforests of Central America. However, the different species play similar roles within their specific regional rainforest.
Flowering plants must be pollinated in order to reproduce. During pollination, pollen is transferred from the male reproductive organs to the female reproductive organs in the flower to form seeds. Many tropical rainforest plants rely on animals as pollinators, and attract them with a combination of flashy color displays, alluring scents, and nutritious pollen rewards. Plants also rely on animals or the wind to help disperse their seeds to new areas. This dispersal expands the distribution of the population. Many plants embed their seeds in tasty fruits. The dispersers might carry the seeds stuck on their fur or feathers, they might carry the fruit away and drop the seeds while eating the fruit, or the seeds might pass through the digestive tract of the disperser after it eats the fruit. The species that carry out these important ecological roles are different in different tropical rainforests. Below are some examples from around the world:
