Classification and Biodiversity

• Why do scientists use scientific names?


  Because common names are different in different countries, and scientific names are universal
• The order of scientific names of organisms

  Genus and species
• Adaptations


  Characteristics of an organism that increase its chance of survival. They are maintained by natural selection
• Organisms require different resources from the environment:

  ● Light

  ● Food

  ● Oxygen

  ● Carbon dioxide

  ● Water

  ● Minerals

  These resources are limited, creating competition between organisms.
• Morphological adaptation


  Structural adaptation e.g. camouflage
• Behavioural adaptation


  Aspect of behaviour that aids survival e.g. bird calls
• Intraspecific competition


  Competition between members of the same species
• Interspecific competition


  Competition between members of different species
• Factors that limit population sizes within a community


  Competition, predation, disease and pollution
