Which ecosystem is the richest in biodiversity?
Amazonia represents the quintessence of biodiversity – the richest ecosystem on earth. Yet a study by Smithsonian scientists, published this week in the journal Science, shows that differences in species composition of tropical forests are greater over distance in Panama than in Amazonia.
Is the temperate forest biodiversity?
Although the biodiversity of temperate forests is typically much lower than that of tropical forests, temperate forest biodiversity hotspots with unique evolutionary histories and with high levels of endemism rival in importance those of either the tropics or the boreal regions.
Do temperate rainforests have high biodiversity?
The Temperate Rainforest Ecosystem
Tropical rainforests have a higher average annual precipitation, but the cooler temperatures of temperate rainforests mean evaporation rates are slower, resulting in a continually damp environment and rich biodiversity.
Which ecosystem is richest in biodiversity Mcq?
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 does temperate forest have a 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 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.
Which rainforest layer supports the greatest biodiversity?
The next layer is the canopy layer, which is known to contain the majority (about 60 to 90%) of living species in the whole rainforest.
