Your question: How much of the world’s biodiversity is in rainforests?

Rainforests are Earth’s oldest living ecosystems, with some surviving in their present form for at least 70 million years. They are incredibly diverse and complex, home to more than half of the world’s plant and animal species—even though they cover just 6% of Earth’s surface.

What percentage (%) of the world’s biodiversity can be found in the rainforest?

RAINFOREST DIVERSITY – ORIGINS AND IMPLICATIONS

Although they cover less than 2 percent of Earth’s surface, rainforests house an estimated 50 percent of all life on the planet’s land masses.

How much of the world’s biodiversity lives in the Amazon rainforest?

Not only does the Amazon encompass the single largest remaining tropical rainforest in the world, it also houses at least 10% of the world’s known biodiversity, including endemic and endangered flora and fauna, and its river accounts for 15-16% of the world’s total river discharge into the oceans.

Are rainforests 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.

What percentage of the world’s plant and animal species can be found in tropical rainforests?

Because tropical rain forests are some of the oldest ecosystems on earth, they are home to a diverse population of plants and animals. In fact, around 50% of the world’s plants and animals can be found here—with new species still being discovered.

Why is biodiversity so high in tropical rainforests?

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.

Why rainforest has a high level of biodiversity?

Rainforests have high biodiversity because they are abundant in nutrients, energy and a favorable climate.

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 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 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.

What are 4 types of biodiversity?

Four Types of Biodiversity

  • Species Diversity. Every ecosystem contains a unique collection of species, all interacting with each other. …
  • Genetic Diversity. Genetic diversity describes how closely related the members of one species are in a given ecosystem. …
  • Ecosystem Diversity. …
  • Functional Diversity.
