Presentation Transcript

  1. Biodiversity Biodiversity: the variety of life in an area. Importance: A species loss may have consequences for other species Animals need plants plants need pollinators Trees need decomposers to restore nutrients Humans depend on other organisms Oxygen is supplied and Co2 is removed by plants and algae Diverse diets Clothing, furniture,and building materials Manufacture Drugs that improve health

  2. Loss of Biodiversity Extinction: the disappearance of a species Passenger pigeons Woodland caribou Leopard frog

  3. Threatened Species Threatened species: a rapid decline of a population of species Elephants Logger-head Turtles Sea Otters

  4. Endangered Species Endangered species: when a species numbers become low enough to become extinct Black Rhinoceros Florida manatees California condor

  5. Threats to Biodiversity Human population growth and development Habitat Loss - cutting down rain forests Habitat fragmentation - highways that separate Habitat degradation - damage by pollution Acid rain: low pH from coal-burning factories & nitrogen oxides from auto exhausts combine with water vapor. Ozone Layer (O3): Chlorofluorocarbons (CFCs) break down ozone layer that protects Earth from UV rays. Water Pollution - Excess fertilizers and wastes Land Pollution - solid wastes Exotic Species Introduced - Take over original population Zebra mussels

  6. Conservation of Biodiversity • Legal Protections of species • Preserving habitats • Reintroduction programs The Gray Wolf

  7. The End Black-footed Ferret
