Transcript

  • 1. Biodiversity in the Ecosystem Presented by: Arnel O. Rivera LPU - Cavite
  • 2. Review:
    • Ecological Niche refers to the set of conditions in the environment in which a species is able to survive and maintain stable population sizes.
    • Ecological Niche is divided into two: fundamental (environmental) and realized (environmental and ecological).
    • Functional traits refers to certain characteristics of species which enables them to survive.
  • 3. Review:
    • Habitat refers to the environment over which a species is known to occur and the type of community that is formed as a result.
    • Population refers to individuals of the same species that live, interact and migrate through the same niche and habitat.
  • 4. Food Chains
    • One of the main features of the ecosystem is biodiversity. Members are usually classified into:
      • Producers – those who can synthesize the organic materials they need from inorganic materials in the environment.
      • Consumers – those that are unable to manufacture their own food directly and depend upon producers to meet their needs.
        • Herbivores
        • Carnivores
        • Omnivores
  • 5.  
  • 6. Food Chains
    • Abstract representation of feeding relationships within a community.
    • The sequence in which energy and nutrients are transferred.
  • 7. FOOD WEB Red Arrows = Energy!
  • 8. Equilibrium
    • Cyclical changes in populations can sometimes result in large fluctuations in the number of a species, but because of the interdependence of all the components, any changes in one part of its nature will result in a reaction in other parts of the community. These reactions work to restore the equilibrium or balance of nature .
  • 9.  
  • 10. Ecological Succession
    • The overall change or disruption in the system’s balance is altered irreversibly and the result is the replacement of one type of ecosystem to another.
  • 11. Carrying Capacity
    • Refers to the maximum number of organisms that can be supported by a particular environment.
    • If the carrying capacity of an ecosystem is exceeded by overpopulation, there will be insufficient resources and one or more species will decline until an equilibrium (balance of nature) is restored.
  • 12. Gala hypothesis
    • The concept that the Earth as a single organism.
    • Formulated by James Lovelock, a British scientist working for NASA.
    • Named after the Greek goddess of the earth.
    • The planet is a self-regulating system in which all the individual elements coexist in a symbiotic relationship.
  • 13. Human Threat
    • Human interference in the Earth’s natural systems has become a major threat damaging the planet’s ecosystem.
    • The damage affected by humans was posing a threat to the viability of the planet itself.
    • The effects of this disruption are now becoming apparent in the changing climates and landscapes of almost every region of the planet.
