Question

define biodiversity ............​

Answer 1

Answer:

Biodiversity is the variety and variability of life on Earth. Biodiversity is typically a measure of variation at the genetic, species, and ecosystem level.[1] Terrestrial biodiversity is usually greater near the equator,[2] which is the result of the warm climate and high primary productivity.[3] Biodiversity is not distributed evenly on Earth, and is richest in the tropics.[4] These tropical forest ecosystems cover less than 10 percent of earth's surface, and contain about 90 percent of the world's species.[5] Marine biodiversity is usually highest along coasts in the Western Pacific, where sea surface temperature is highest, and in the mid-latitudinal band in all oceans.[6] There are latitudinal gradients in species diversity.[6] Biodiversity generally tends to cluster in hotspots,[7] and has been increasing through time,[8][9] but will be likely to slow in the future.[10]

• Biodiversity is used to describe the total number of different species within an ecosystem.
• Coral reefs have the most diversity of all ecosystems on Earth.
• Biodiversity is very important to an ecosystem because each species plays a different role in the maintenance of the ecosystem.
• About .1% of species are lost each year.
