Is biodiversity evenly or unevenly distributed?
Biodiversity is a measure of variation at the genetic, species, and ecosystem level. Terrestrial biodiversity is usually greater near the equator, which is the result of the warm climate and high primary productivity. Biodiversity is not distributed evenly on Earth, and is richer in the tropics.
Is biodiversity equally distributed over the Earth explain?
How biodiversity is distributed on Earth? Biodiversity is not evenly distributed, rather it varies greatly across the globe as well as within regions. Among other factors, the diversity of all living things (biota) depends on temperature, precipitation, altitude, soils, geography and the presence of other species.
Is biodiversity the same everywhere?
Some areas in the world, such as areas of Mexico, South Africa, Brazil, the southwestern United States, and Madagascar, have more biodiversity than others. Areas with extremely high levels of biodiversity are called hotspots.
Are species evenly distributed?

What is the meaning of uneven distribution?
adjective [usually ADJECTIVE noun] An unequal system or situation is unfair because it gives more power or privileges to one person or group of people than to others. unequally adverb [ADVERB with verb]
Why are organisms not evenly distributed across the earth?
Temperature and rainfall are two of the things that drive the distributions of organisms. … They can physically restrict organisms to a particular place. Mountain ranges, even rivers, can be barriers in a terrestrial environment. Some organisms can’t cross them.
What do you mean by uneven distribution of population?
World population distribution is uneven. Places which are sparsely populated contain few people. Places which are densely populated contain many people. Sparsely populated places tend to be difficult places to live. … Population distribution is also uneven within a country.
What do you understand by biodiversity explain the need of biodiversity?
The term biodiversity (from “biological diversity”) refers to the variety of life on Earth at all its levels, from genes to ecosystems, and can encompass the evolutionary, ecological, and cultural processes that sustain life.
Which of the following correctly defines biodiversity?
Biodiversity is the variability among living organisms from all sources, including terrestrial, marine, and other aquatic ecosystems and the ecological complexes of which they are part; this includes diversity within species, between species, and of ecosystems.
What is population in biodiversity?
A group of individuals of the same species, occupying a defined area, and usually isolated to some degree from other similar groups. Populations can be relatively reproductively isolated and adapted to local environments. … Population is here defined as the total number of individuals of the taxon.
