Introduction to Biology and the Study of Life
3
What is Biology?
  • Biology is the study of organisms.
  • Bio life
  • ology study of
  • Organism

4
We call these different fields of Biological
study, Branches__ of Biology.
  • Zoology study of animals
  • Microbiology study of microorganisms
  • Botany study of plants
  • Ornithology study of birds
  • Ichthyology study of fish
  • Herpetology study of reptiles and amphibians
  • Virology study of viruses
  • Entomology study of insects
  • Mycology study of fungi

Part 1 What is Ecology?
6
What is Ecology?
  • Ecology is the study of how organisms interact
    with each other and how they interact with their
    environment.

7
What is Ecology?
  • Ecology is the study of how organisms interact
    with each other and how they interact with their
    environment.
  • An organisms environment is all the non-living
    and living things that make-up its surroundings.

The Environment
  • Abiotic Factors
  • Non-living factors
  • A - not

Part 2 Ecological Levels of Organization
11
Ecological Levels of Organization
  • Brainstorm Why have ecologists organized the
    study of ecology into levels?

12
Ecological Levels of Organization
  • Why have ecologists organized the study of
    ecology into levels?
  • Organization allows for
  • A better understanding of the material.

13
Ecological Levels of Organization
  • Why have ecologists organized the study of
    ecology into levels?
  • Organization allows for
  • A better understanding of the material.
  • Quick and easy access to information.

14
Ecological Levels of Organization
  • Most Specific
  • Organism ?

15
Ecological Levels of Organization
  • Organism ? Species ?

16
Ecological Levels of Organization
  • Organism ? Species ? Population ?

17
Ecological Levels of Organization
  • Organism ? Species ? Population ?
  • Community ?

18
Ecological Levels of Organization
  • Organism ? Species ? Population ?
  • Community ? Ecosystem

19
Ecological Levels of Organization
  • Organism ? Species ? Population ?
  • most inclusive
  • Community ? Ecosystem ? Biome

Ecological Levels of Organization
  • specific
  • 1. Organism A living thing

21
Ecological Levels of Organization
  • 1. Organism A living thing
  • 2. Species A group of organisms that are so
    similar to one another, they can breed/reproduce
    and have fertile offspring, offspring that can
    also reproduce and have offspring.

Ecological Levels of Organization
  • 1. Organism A living thing
  • 2. Species A group of organisms that are so
    similar to one another, they can breed/reproduce
    and have fertile offspring, offspring that can
    also reproduce and have offspring.
  • 3. Population A species, or group of similar
    organisms, that live in the same area at the same
    point in time.

  • 3. Population A species, or group of similar
    organisms, that live in the same area at the same

  • 4. Community A group of different populations
    that live in a defined area.

Ecology Term Practice
  • The Appalachian Trail (AT) is the longest hiking
    trail in the nation. It is approximately 2,178
    miles long and on average takes three months to
    hike. One end of the Appalachian Trail is located
    in Northeastern Georgia just seven miles away
    from the city of Atlanta, while the other end is
    located in Maine. While hiking the AT, it is
    common for hikers to come across mountain lions,
    bob cats, squirrels, cottontail deer, and even
    black bear. The Eastern Gray Squirrel can be a
    source of food for mountain lions and bob cats.
    The Gray Squirrel usually makes its home in oak
    trees. It lives in the holes drilled by
    woodpeckers. It spends most of its time finding
    and burying nuts, as its main source of food is
    hickory nuts, acorns, and/or walnuts. Depending
    on the time of year, hikers may experience heavy
    rain or even snow. Many hikers will tell you the
    trail is a formidable opponent, because of its
    steep rocky climbs and slippery muddy terrain
    after a heavy rain.
