Title: Exciting and Excellent Ecology!


1
Exciting and Excellent Ecology!
2
What do you think of when you hear ECOLOGY?
3
What is Ecology?
  • Ecology is the scientific study of interactions
    between organisms and their environments.
  • Scientists study the relationships between the
    living and nonliving parts of the world.

4
The Living Environment Biotic Factors
  • The BIOSPHERE is the portion of Earth that
    supports life!
  • It extends from the atmosphere to the bottom of
    the oceans!
  • If you shrank the Earth down to the size of an
    apple, the biosphere would be thinner than the
    apples peel!

5
The Living Environment Biotic Factors
  • All the living factors that inhabit an
    environment are BIOTIC FACTORS!
  • Think BIO from BIOLOGY (the study of life) must
    mean living things!
  • Different organisms are adapted to different
    parts of the biosphere.
  • EX Fish, Mountain Goats, Moles

6
The Nonliving Environment Abiotic Factors
  • Ecologists study how nonliving factors in the
    environment affect living things.
  • ABIOTIC FACTORS are the nonliving parts of the
    environment.
  • Examples air currents, temperature, moisture,
    light, and soil.
  • Abiotic factors can determine which species can
    survive in a particular environment!

Levels of OrganizationThe Hierarchy of Life!
  • ORGANISMS
  • POPULATIONS
  • COMMUNITIES
  • ECOSYSTEMS
  • BIOSPHERE

10
What are ecosystems?
  • Interactions among living things and abiotic
    factors form ecosystems.
  • Ex Terrestrial ecosystems on land are forests,
    meadows, and deserts.
  • Ex Aquatic ecosystems in water are fresh or salt
    water environments.
  • What does your ecosystem consist of?

11
Where and How Organisms Live
  • Every species has a particular function in its
    community-this is called its NICHE.
  • A HABITAT is the place where an organism lives
    out its life.
  • What is your HABITAT and NICHE right now?

12
Species Relationships!Whos HOT and Whos NOT!
  • FEEDING RELATIONSHIPS
  • -AUTOTROPHS-make their own food
  • Ex Plants
  • -HETEROTROPHS-rely on autotrophs
  • Ex Rabbits, Cows, etc.
  • -SCAVENGERS-Feed on carrion, refuse, and dead
    organisms
  • Ex Vultures, hyenas

13
Species Relationships!Whos HOT and Whos NOT!
  • MORE FEEDING RELATIONSHIPS
  • -DECOMPOSERS-break down and absorb nutrients from
    dead organisms
  • Ex Bacteria, Fungi, etc.

14
SYMBIOSIS-Living TogetherNot always happily
ever after!
  • COMMENSALISM-one species benefits and the other
    is not harmed or benefited
  • Ex Peregrine Falcon Red-breasted Goose
  • MUTUALISM-both species benefit! ?
  • Ex Ant Acacia Tree
  • PARASITISM-one species benefits at the expense of
    the other ?
  • Ex Ticks/Fleas Dogs

istic relationships,and Parasitic relationships
