biodiversity Flashcards
(11 cards)
what is biodiversity
a measure of all the species worldwide, the genes they contain and the habitats of which they form a part
a measure of how varied an ecosystem is
types of biodiversity
genetic, species, habitat
genetic diversity
variations in genetic code
species diveristy
how many different species in an area
habitat diversity
how many different habitats in an area
what is a species
a group of organisms with similar anatomy, physiology, biochemistry, genetics as well as behavioural characteristics
can interbreed to produce fertile offspring
hybrids
interbreed to produce infertile offspring
species richness
the number of species
what is a habitat
range of physical, biological and other environmental factors within which a species can survive
species eveness
the abundance of individuals in each species
the importance of genetic biodiversity
species with greater genetic biodiversity are more likely to adapt to changes in their environment and therefore less likely to go extinct
