Title: Ecology Stem Words


1
EcologyStem Words
  • ECO House/Home
  • LOGY The science of OR the study of
  • Eco logy The study of home - where things
    live.

2
The study of the relationships living things have
with each other and to their environment.
3
Biotic Factors
  • Biotic Factors - all of the LIVING things in an
    ecosystem
  • (living now or once was living)
  • Stem word BIO
  • life or living

4
Abiotic Factors
  • Abiotic Factors all the NON-LIVING parts of an
    ecosystem
  • Examples
  • Water
  • Sunlight
  • Soil
  • Air, Oxygen
  • Temperature

5
How Living and Non-Living things are Organized on
Earth
  • From Largest to Smallest
  • 1. Biome ? 2.Ecosystems ?
  • 3.Communities ? 4.Populations?
  • 5.Individual Organism

6
Biome
  • Biome a group of ecosystems with similar
    climates and organisms
  • Examples of Biomes
  • Tropical Rain Forests
  • Tundra
  • Grassland
  • Desert
  • Ocean (marine)
  • Deciduous Forest

8
The Tundra Biome is a cold dry place where no
trees live.

Coniferous Forest (Tiaga)
14
Ecosystems -
  • Contains ALL the living AND non-living things
    that interact in a particular area.

15
Communities -
  • ALL the different populations of organisms within
    an area.

16
Populations
  • ALL the members of one species in a particular
    area.
  • Its a NUMBER count. Does not matter how big or
    small the area is.
  • World Population
  • South Carolina Pop.
  • Greenwood Pop.
  • EMS Population

17
Species
  • Organisms that are physically similar
  • Can mate to produce FERTILE offspring.
  • Fertile means their babies can have babies.
  • Similar DNA (genetics)

18
Examples of a SpeciesDogs - Different dog
breeds can mate to give mixed breed that look
like both parents AND the mixed puppies can have
babies themselves. Cats Humans Horses
19
  • Examples of Non-Species
  • Horse Donkey Mule (Sterile)
  • Lion Tiger Liger (Sterile)
  • Zebra Horse Zorse (Sterile)
  • Sterile cannot have babies

20
Horse Donkey A Mule (AKA Honkey)(A animal
that is STERILE cannot breed




21
Lion Tiger A Liger(A sterile animal cannot
breed)

22
Liger
23
Horse Zebra Zorse(A sterile animal cannot
breed)

25
Habitats
  • Habitats The place where an organism lives and
    can find the things it needs to survive.
  • Needs for Survival
  • Food
  • Water
  • Shelter
  • Space

26
How big does an organisms habitat need to be?
  • Depends on size of animal.
  • Examples
  • Squirrel backyard
  • Whale ocean
  • Fish pond
  • Single ecosystem contains 1000s of habitats

27
A single ecosystem can contain many habitats.
28
Changes in Population Size(Positive and Negative)
  • Births and Deaths
  • Immigration and Emmigration
  • Immigration moving into a population
  • Emmigration - moving out of a population
  • 3. Limiting Factors

29
Limiting Factors
  • An environmental factor that causes a population
    to DECREASE or stop growing.

30
  • Food/water starvation
  • 2. Disease/accidents
  • 3. Shelter/Weather
  • 4.Predators/Hunters
  • 5. Space

31
Competition over space
32
Birth/Death Rates
33
What happens to Moose population as Wolf
population increases?

Carrying Capacity
  • Carrying Capacity the largest population an
    environment can support.
