Why is biodiversity so high in tropical rainforests quizlet?
Biodiversity is high because the warm and wet consistent climate in tropical rainforests is able to sustain life in all different forms. … Temperature and precipitation allow you to determine the quality of the soil in the region, which result in an ability to determine the ability of the region to sustain life.
What is special about the biodiversity in tropical rainforests?
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 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.
Why are tropical forests so 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’ …
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 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.
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.
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.
