  2. Ecology is the study of the relationships between the natural world and all the living and non-living things in that environment

  3. Levels of organization in Ecology • Biosphere • Ecosystem • Community • Population • Individual (species)

  4. SPECIES • Similar organisms that can successfully reproduce among themselves in their natural environment • THIS MEANS: they produce offspring that can reproduce as well Examples: Species of frog: water frog, red-eyed tree frog • Species of horse: Clydesdale horses, Andalusian horses

  5. POPULATION • A population is made of many of the SAME KIND of species that live in the same area • Compete with each other for food, mates, water and space Examples • Population of trout in a river • Population of bats living in a cave • Population of GI students in the classroom

  6. COMMUNITY • A community is made of many groups of populations that interact in an area Examples: • A forest: populations of trees, populations of mushrooms, populations of birds • A lake: populations of insects, populations of fish, populations of algae

  7. ECOSYSTEM • An ecosystem includes all the living organisms in an area and all the non- living things that affect it Examples: • Forest ecosystem includes grass, soil, wind, sunlight, animals • Ocean ecosystem includes fish, coral, rocks at the bottom, temperature of water

  8. BIOSPHERE • The part of the Earth that supports all organisms, made up of all of the Earth’s ecosystems Examples: • Made up of the water, land, living things and air

  9. Levels of Organization

  10. Science Journal • SJ: Why do you think the ecological model (in the note today) is a picture of circles within circles?
