taxonomy and biodiversity

• courtship behaviours enable species to recognise each other as the same species, synchronise mating, form a pair bond, become able to breed
• Classification is the process of naming and organising organisms into groups based on their characteristics
• animals cab be grouped further into domain (archae, eukaryotes and prokaryotes)kingdom, phylum, class, order, family, genus and species.
• Biodiversity is the variety of living organisms.
• Species diversity is the number of different species and the number of different individuals in a community.
• Ecosystem diversity is the range of different habitats.
• habitat is the place where an organism lives
• population is number of organisms of the same species that live in a particular area at the same time
• monoculture is an area with only a single species, this limits biodiversity
• index of biodiversity is a mathmatical measure of species diversity in a given community, this is based of species richness and species abundance
• farming reduces biodiversity by reducing number of alleles
• we can increase biodiversity in farming by using hedgerows instead of fences, growing variety of crops, reducing use of herbicides and pesticides and preserving wetland habitats
