Why Are Tropical Rainforests So Rich In 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. … Plants which are primary producers can be limited by many things such as precipitation sunlight nitrogen soil conditions and etc.Mar 21 2017
Why do tropical areas have more biodiversity?
The higher temperatures in the tropics cause higher rates of metabolism ecological dynamics and coevolutionary processes which generate and maintain higher biodiversity.
What is special about the biodiversity 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.
Do tropical rainforests have high biodiversity?
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 tropical regions are richer in biodiversity than the temperate regions?
It is generally seen that there is more biodiversity in the tropical region than the temperate region because of a variety of factors: … The tropical forest has a stable ecosystem as well as a suitable climatic condition and favorable reproductive environment for animal and species to thrive.
Why wet tropical rainforest is rich in diversity as compared to temperate rainforest?
Ample sunlight consistently warm temperatures and frequent abundant precipitation — all plentiful in tropical rainforests — tend to produce highest biodiversity among ecosystems.
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.
How does the rainforest support such a high biodiversity?
Rainforests have an abundance of plants and animals for the following reasons: Climate: because rainforests are located in tropical regions they receive a lot of sunlight. … This energy is stored in plant vegetation which is eaten by animals. The abundance of energy supports an abundance of plant and animal species.
Which has more biodiversity a rainforest or a desert?
Both biomes have warm climates but the desert is very dry and the rainforest is very wet. The desert has very few organisms so it has low biodiversity. … In contrast the rainforest has the highest biodiversity of any biome on Earth.
Why are rainforests important for biodiversity?
Rainforests contain about half of the existing plant and animal species in the world. They contain a third of the world’s bird species and 90% of its invertebrates. The remaining African rainforests contain more animals and plant species than are found anywhere else on the continent.
Why do tropical rainforest have high productivity?
In Tropical Rainforests water sunlight and high temperatures are consistent and a dense concentration of plants is present causing both the GPP and NPP to be very high. So high levels of productivity increase biomass.
Why is there so little biodiversity in desert biomes?
Plants animals and other organisms that live in deserts have evolved to survive harsh conditions scarce water and barren landscapes. … This desertification is exacerbated by human exploitation of ecosystems that border deserts causing land degradation soil erosion and sterility and a loss of biodiversity.
Which region is rich in biodiversity?
Answer : Option (A) is correct because biodiversity is richer in tropical regions. Tropical forest ecosystems cover less than 10 percent of earth’s surface and contain about 90% of the world’s species.
Why are tropical forests diverse?
Perhaps they posited the astonishing plant diversity we find in tropical forests is enabled by two factors: the presence of “natural enemies” that target specific species and keep population size in check and the tendency of youngsters of one species to settle far away from their parents beyond those predators’ …
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 was a major difference in the biodiversity between the temperate and tropical forests?
What was a major difference in the biodiversity between the temperate and tropical forests? 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 is biodiversity so low in tundra and desert biomes?
Because of these low temperatures and short growing seasons net primary productivity is very low in the tundra between 100–200 g m–2 yr–1. … Biodiversity in the tundra is low and dominated by mosses lichens and low-growing perennial shrubs.
Which adaptation is most likely found in tropical trees Brainly?
The leaves of forest trees have adapted to cope with exceptionally high rainfall. Many tropical rainforest leaves have a drip tip. It is thought that these drip tips enable rain drops to run off quickly. Plants need to shed water to avoid growth of fungus and bacteria in the warm wet tropical rainforest.
Why do most soils in tropical rain forests hold few plant nutrients?
Why do most soils in tropical rain forests hold few plant nutrients? There is lost of decomposers and the warmth causes decomposition to take place very quickly what nutrients are left are quickly taken up trees vines or other plants. While the daily rainfall leech the thin topsoil and take away the nutrients.
Why does a rainforest allow for specialized niches?
The reason for this occurrence is that the majority of rainforest species are scarce over the range of the forest and may be common in only a few small areas where they are particularly well adapted. … The reason for this pattern is that many species are highly specialized to fit a particular niche.
Why does the rainforest contain 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.
Why does vegetation in tropical rainforests differ from the vegetation in deserts?
Some desert plants have very deep root system in order to absorb water from near the water table. Rainforest plants have specialized roots that are more adapted to support the trees as trees are often unstable due to the wet and loose soil. … They have more diversity than desert plants. They do not experience much rain.
Why is biodiversity in an ecosystem so important?
Why are tropical rainforests valuable?
Rainforests are often called the lungs of the planet for their role in absorbing carbon dioxide a greenhouse gas and increasing local humidity. Rainforests also stabilize climate house incredible amounts of plants and wildlife and produce nourishing rainfall all around the planet.
What causes high biodiversity?
Ecosystems that host the most biodiversity tend to have ideal environmental conditions for plant growth like the warm and wet climate of tropical regions. Ecosystems can also contain species too small to see with the naked eye.
Why are tropical wet forests and estuaries most productive?
Tropical Rainforests have high primary productivity because of availability of plenty of solar light and water. A typical estuary has high primary productivity because it is shallow (gets plenty of sunlight) and has turbulent water (which brings the nutrient rich material from sea bed).
Why are tropical rainforests the sites of highest primary production in a terrestrial environment?
Tropical rain forests have high NPP and the highest biodiversities of any terrestrial ecosystems. … In rain forests plants have constant high levels of water and light (at canopy level) and the nutrient supply is as high as possible due to rapid decomposition.
Are rainforests the most productive and most complex ecosystems on Earth?
Rainforests cover less than two percent of the Earth’s surface. They are home to some 50 to 70 percent of all life forms on our planet. Rainforests are the most productive and most complex ecosystems on Earth.
Why is biodiversity so low in the hot desert?
There is very little biodiversity in hot deserts because of the harsh climate. Few species are specialised enough to survive there. Plants and animals which do survive there have adapted to difficult conditions.
Is the biodiversity high or low in the desert?
Which ecosystem has high biodiversity low biodiversity?
Estuarine areas (where rivers meet seas and oceans) have high biodiversity compared to other areas. Trophical rainforests are rich in terms of biodiversity. Arid and semiarid areas have low biodiversity. Deserts for example contain limited numbers of species.
Which of the following is rich in biodiversity?
Largest region is Deccan Peninsula and most biodiversity rich region is Western Ghats (4%) with a very large number of endemic amphibian species.
Why is the most biodiversity found near the equator?
There might be more biodiversity near the equator because it’s warmer year round allowing organisms to continue growing. Locations away from the equator will have cold winters that will slow growth for microorganisms plants and animals.
Why is biodiversity high in the tropics?
– Tropical latitudes produce more solar power than temperate zones resulting in high productivity and high diversity of biodiversity. – There are fewer seasonal changes in tropical regions and they have a more or less stable climate. This encourages the specialization of the niche and hence the high wealth of animals.
Why Do More Species Live Near the Equator?
