Group of organisms capable of breeding to produce living, fertile offspring.
What is the binomial naming system?
Used to name species in two parts:
genus - generic name
species - specific name
Process of naming and organising organisms into groups based on their characteristics.
What is molecular phylogeny?
The analysis of molecular differences in different organisms to determine their extent of evolutionary relatedness.
Why is courtship behaviour important?
So that organisms find other members of the same species to produce fertile offspring.
What are the different types of courtship behaviour?
Recognition of own species
The taxonomical classification of organisms in successive levels of complexity from Kingdom to Species.
What is biodiversity?
The variety of living organisms.
How can biodiversity be measured?
Ecosystem diversity - range of different habitats
Species diversity - number of different species + individuals in a community
Genetic diversity - genetic variation, number of alleles in gene pool
What are the factors affecting biodiversity?
Invasion of alien species -
Habitat loss/fragmentation -
