Biodiversity: Tropical rainforests are areas of extremely high biodiversity compared to other ecosystems. … 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.
Why does the rainforest have high biodiversity?
The high species richness or biodiversity found in tropical rain forests is mainly due to their geographic location and the amount of precipitation they receive. Tropical rainforests fall along the equator and receive a large amount of precipitation.
Do rainforests have more diversity?
Tropical rainforests support the greatest diversity of living organisms on Earth. Although they cover less than 2 percent of Earth’s surface, rainforests house more than 50 percent of all plants and animals found on land. … Rainforests have 170,000 of the world’s 250,000 known plant species.
How much biodiversity is in tropical rainforests?
Tropical rainforests are the most biologically diverse terrestrial ecosystems in the world. The Amazon rainforest is the world’s largest tropical rainforest. It is home to around 40,000 plant species, nearly 1,300 bird species, 3,000 types of fish, 427 species of mammals, and 2.5 million different insects.
Does a rainforest have more biodiversity than a desert?
Explanation:RAINFOREST shows more biodiversity because it has suffecient amount of all resources needed all types of species. … This also tells us rainforest is best place for many animals.
What is the biodiversity in the Amazon rainforest?
The Amazon Rainforest and Biodiversity
As an ecosystem, the Amazon is one of the most biodiverse places on earth. Over 3 million species live in the rainforest, and over 2,500 tree species (or one-third of all tropical trees that exist on earth) help to create and sustain this vibrant ecosystem.
Why is the biodiversity of a tropical rainforest very high quizlet?
Biodiversity is high because the warm and wet consistent climate in tropical rainforests is able to sustain life in all different forms. Soil nutrient is poor in tropical rain forests because the sunlight that is intended to reach the floor of the tropical forest is blocked by the tall and dense trees.
Why are tropical areas more diverse?
The higher temperatures in the tropics cause higher rates of metabolism, ecological dynamics and coevolutionary processes, which generate and maintain higher biodiversity.
Which ecosystem has highest biodiversity?
Coral reefs are believed by many to have the highest biodiversity of any ecosystem on the planet—even more than a tropical rainforest. Occupying less than one percent of the ocean floor, coral reefs are home to more than 25% of all marine life.
Which biome has the least amount of biodiversity?
Of the three forest biomes, the taiga has the lowest biodiversity.
How do rainforests affect ecology?
How do rain forests influence ecology? Rain forests can take up large amounts of carbon dioxide and so act as a buffer against climate change. Which of the following is NOT true about the interaction of sunlight with Earth? … Some sunlight is reflected off the atmosphere without heating Earth.
Why do deserts have low biodiversity?
Biodiversity is low in hot desert ecosystems. There are far fewer species supported by the extreme climate compared to other biomes. This is due to the high temperatures, low rainfall and a lack of available water. … Human activity is the greatest threat to biodiversity in hot deserts.
How are deserts and rainforests different?
The deserts are very dry land areas that can be hot or cold and experience very less rainfall. On the other hand, rainforests receive an enormous amount of rain. Both are homes to a variety of plants.
