Gen bio

• Biodiversity


  The variety of earth's species, the genes they contain, the ecosystems in which they live, and the ecosystems processes such as energy flow and nutrient cycling that sustain all life
• Biodiversity is a vital renewable resource
• Biodiversity sustains us and our economies
• Major components of earth's biodiversity

  • Functional diversity
  • Ecological diversity
  • Genetic diversity
  • Species diversity
• Functional diversity


  The biological and chemical processes such as energy flow and matter recycling needed for survival of species, communities, and ecosystems
• Ecological diversity


  The variety of terrestrial and aquatic ecosystems found in an area or on the earth
• Genetic diversity


  The variety of genetic material within a species or a population
• Species diversity


  The number and abundance of species present in different communities
• Biological Evolution by Natural Selection


  Explains how life changes over time
• What explains how life has changed over the last 3.5 billion years

  • Study of the Fossil Record
  • Biological Evolution (genes changing in populations)
  • Natural Selection (certain traits out survive others)
