Ecology

1
Ecology

• Ecology is an integrated and dynamic study of the
  environment and the organisms that inhabit it.

2
Origin of Ecology

• Greek origin of the word
• OIKOS household
• LOGOS study of
• Ecology is the study of the house/environment
  in which we live.

ECOLOGY Levels of Organization

• - a hierarchy of organization
• in the environment

4
Ecological Levels of Organization
5
Levels of Organization

• Organism- one individual (living)
• Ex A moose

6
Levels of Organization

• Population- groups of individuals that belong to
  the same species and live in the same area.
• Ex Many moose

7
Levels of Organization

• Community- groups of different populations (more
  than one population or different groups of
  species)
• Ex Many groups of moose beavers, trees, grass
  (all living)

8
Habitat vs. Niche

• Habitat- an area where an organism lives.
• Niche- the role an organism plays in its
  environment.
• Habitat is like an address in an ecosystem and a
  niche is like an occupation in an ecosystem.

9
Levels of Organization

• Ecosystem- all organisms in a particular area
  along with the nonliving factors (abiotic).
• Ex Many groups of moose, beavers, trees, grass,
  rocks, water, mountains

10
Levels of Organization

• Biome- group of ecosystems that have the same
  climate and similar dominant communities
• Ex tropical rain forest, tropical savanna,
  temperate grassland, desert, deciduous forest,
  temperate forest, northwestern coniferous forest,
  boreal forest (taiga), tundra, and ice caps

11
Levels of Organization

• Biosphere- all of the planet where life exists,
  includes land, water, and air.
• Life extends 8 km above and 11 km below the
  surface of the Earth.

12
Ecology

• views each locale as an integrated whole of
  interdependent parts that function as a single
  unit.

13
The interdependent parts are
14

• Nonliving
• Sunlight
• nutrients in the soil and water.
• Producers (autotrophs)
• green plants

Tundra
15

• Consumers (heterotrophs)
• herbivores and carnivores
• Decomposers (detritivores)
• fungi and bacteria

Fungi
Caribou

What shapes an ecosystem?

• This includes the interactions between non-living
  and living components of our environment.
• Abiotic non-living components in the
  environment
• Sunlight
• Water
• Wind
• Nutrients in soil
• Heat
• Humidity
• Solar radiation
• Atmosphere, etc.

17
What shapes an ecosystem?

• Biotic Living Components of the environment
• Plants
• Animals
• Bacteria
• Arthropods
• Organisms that
• were once living

18
Poster project

• Pick something relevant to you, ie. Your favorite
  book, comic book, video game, etc., Must have
  picture for each level
• Create a levels of organization poster showing
  how it is organized from organism to biosphere.
• Must have definition about each level and state
  if it has Biotic or Abiotic factors or both and
  explain what those words mean
