Ample sunlight, consistently warm temperatures and frequent, abundant precipitation — all plentiful in tropical rainforests — tend to produce highest biodiversity among ecosystems.
Why does a rainforest have more biodiversity?
Explanation: 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.
What has a higher biodiversity a rainforest or a temperate forest?
No one knows exactly how many species live in the world’s tropical rainforests — estimates range from 3 to 50 million species — rainforests are the undisputed champions of biodiversity among the world’s ecosystems, containing far higher numbers of species on a per-area basis relative to sub-tropical, temperate, and …
Do temperate forests have high biodiversity?
Fortunatly most temperate decidous forests have a very high biodiversity index. This is because the biome houses a very high density of plant life. This high density forest contians a countless number of species of deciduous trees which also house a countless number of animal species.
Why is there more biodiversity in tropical regions than temperate region?
“There is greater biodiversity in tropical/subtropical regions than in temperate region. … The tropical/subtropical region exhibit maximum biological diversity because these region remain undisturbed due to less variable climatic conditions. So, tropics has a longer evolutionary time for species diversification.
What is the biodiversity of tropical rainforest?
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.
Why do tropical rainforests have high productivity and why do tropical rainforests have high biodiversity?
Climate: because rainforests are located in tropical regions, they receive a lot of sunlight. … Since there is a lot of sunlight, there is a lot of energy in the rainforest. This energy is stored in plant vegetation, which is eaten by animals. The abundance of energy supports an abundance of plant and animal species.
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.
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.
How do tropical rainforest ecosystems differ from other forest ecosystem?
A forest ecosystem must receive over 60 inches of rain per year to be considered a rainforest. … The tropical rainforest biome is home to over 50 percent of all known species of living things, the vast majority of which live in the canopy. The temperate rainforest biome has fewer species due to its cooler climate.
Why are the tropics more diverse than temperate deciduous forests?
Why are the tropics more diverse than temperate deciduous forests? Ample sunlight, consistently warm temperatures and frequent, abundant precipitation — all plentiful in tropical rainforests — tend to produce highest biodiversity among ecosystems.
What is the difference between temperate forests from tropical forest?
There are two types of rainforests, tropical and temperate. Tropical rainforests are found closer to the equator where it is warm. Temperate rainforests are found near the cooler coastal areas further north or south of the equator. The tropical rainforest is a hot, moist biome where it rains all year long.
How does the biodiversity of the boreal forest biome differ from that of the tropical rainforest biome?
The boreal forest biome has much lower biodiversity than the tropical rainforest biome. Typically just a few species of trees dominate the boreal forest. Cold temperatures and day length (photoperiod) likely limit NPP in a boreal forest. Describe the vegetation found in a tropical scrub biome.
Why is there less diversity in temperate region?
What is the reason for this difference? Tropical and temperate areas have seen different rates and timing of habitat loss. The major cause of biodiversity loss in recent times is habitat destruction and degradation. … Temperate areas had already lost over half their broadleaf forests by 1950.
What are the reasons for greater biodiversity?
There are three different reasons which explain why there is species richness in the tropics.
- Tropical latitudes receive more solar energy than temperate regions, which leads to high productivity and high species diversity.
- Tropical regions have less seasonal variations and have a more or less constant environment.
Why is tropical environment able to support greater species diversity give two reasons?
Tropical environments, unlike temperate ones, are less seasonal, relatively more constant and predictable. Such constant environments promote niche specialization and lead to a greater species diversity.
