However, current understanding of biodiversity includes other components, such as the number, abundance, composition, and spatial distribution of species and functional groups. Biodiversity affects the health of ecosystems, allows life to adapt to environmental changes and evolve, and cycles energy and nutrients. Wood, fibres, perfumes, lubricants, rubber, resins, poison and cork are all derived from . - An indicator species is an organism used to assess a specific environmental condition. 5 What are the four main causes of biodiversity? If a species is genetically unique — if, for instance, it's far out on a remote arm of the evolutionary tree, like the distinctive, peculiar platypus — its biodiversity value is greater than that of a species clustered with many similar species because it preserves a unique part of the . Genetic diversity - refers to the genetic variation that occurs among members of the same species. What happens to an ecosystem when biodiversity decreases? Genes, species, and ecosystems of direct, indirect, or potential use to humanity are often referred to as "biological resources" (McNeely and others 1990; Reid and Miller 1989; Wood 1997). The diversity of life forms in an environment. 3.4.4.1. Biodiversity is important because it allows for organisms to adapt to their environment, and to survive dramatic environmental changes. 4. - Genes, species, ecosystems, and ecosystem process. The earth's variety of species contains an even greater variety of The soil is rich in organic matter and nutrients, which support the growth of trees. C.4 U.5 Biogeographic factors affect species diversity. Three components of biodiversity are ecosystem, species and genetic diversity. Even knowledge of taxonomic diversity, the best known dimension of biodiversity, is incomplete and strongly biased toward the species level, megafauna, temperate systems, and components used by people.

The loss of populations, species, or groups of species from an ecosystem can upset its normal function and disrupt these ecological services. Hence, an ecosystem is a collection of living components and non-living components that are connected by energy flow. We further analysed the dataset to explore which components of biodiversity were most commonly linked with which dimensions of poverty. C4.4 Ex situ conservation is the preservation of species outside their natural habitats C4.5 Biogeographic factors affect species diversity. What are the components of biodiversity? Still stuck? The four reasons include Loss of habitat and fragmentation, Over-exploitation of species, Invasion of alien (new) species and Co-extinctions.
