14Ecosystems -
- Contains ALL the living AND non-living things
that interact in a particular area.
15Communities -
- ALL the different populations of organisms within
an area.
16Populations
- 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
-
17Species
- Organisms that are physically similar
- Can mate to produce FERTILE offspring.
- Fertile means their babies can have babies.
- Similar DNA (genetics)
18Examples 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

- Space
26How 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
27A single ecosystem can contain many habitats.
28Changes 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
29Limiting 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
31Competition over space
