Transcript

  • 1. Ecology Module 2
  • 2. Ecology
    • The study of interactions between organisms and their environment
    • Those that study ecology are ecologists
  • 3. Organization of Life
  • 4. Organization of Life
    • All living matter can be organized
      • SMALLEST--> LARGEST.
      • Ecology deals with the levels
        • Organisms
        • Populations
        • Communities
        • Ecosystems
        • Biomes
        • Biosphere
  • 5. Organisms
    • Ecologists may study the behavior on an individual organism .
      • They may study its daily movements, feeding, or breeding behaviors.
    • Ex
      • A deer
      • A Shark
  • 6. Populations
    • A group of organisms of one species that interbreed and live in the same place at the same time.
      • Compete for food, water, mates, and other resources
      • Resources determine how big/small a population is
    • They may also study growth rates of populations and predict future populations
    • Ex
      • Many deer
      • Endangered species
  • 7. Communities
    • A collection of interacting populations
      • All organisms in a community depend in someway on the other organisms living there.
      • Ecologists are concerned with studying the effects on the community when a new species is added or removed.
    • Ex
      • Hawks go up then mice go down
  • 8. Ecosystem
    • All the biotic and abiotic factors in an area from an ecosystem .
      • Ecologists are concerned with ecosystem stability and knowing what keeps ecosystems stable.
      • Ex
        • Rain forest
  • 9. Biome
    • A group of ecosystems that together make up a specific region for species to live
    • Similar climate
      • Temperature
      • Elevation
      • Rainfall
  • 10. Biosphere
    • The biosphere is the highest level of organization.
    • It is made up of the entire planet and all its living and nonliving parts
    • Ecologists are concerned with all interactions within the biosphere.
  • 11. Living environment= Biotic factors
    • Living things are found in air, on land, in both fresh and salt water
    • The Biosphere is the portion of the Earth that supports life
    • Biotic factors= all living organisms
  • 12.  
  • 13. Nonliving factors= Abiotic Factors
    • Environment
      • Air currents
      • Temperature
      • Moisture
      • Light
      • Soil
  • 14.  
  • 15. Where and how organisms live
    • Every species has a particular function in its community
      • A Niche is the role a species plays in a community
      • The space, food, and other conditions an organism needs to survive and reproduce are part of it’s niche
        • Ex
          • Fungi= break down of organic matter
          • Coyotes= keep rodents down
  • 16.  
  • 17. Habitat
    • A place where organism lives out its life
      • Ex bird in trees
      • Prairie dog in grassland burrows
      • Several species share habitats , the food, shelter and other resources of that habitat are divided into separate niches
