What is an organism?

• A living thing is referred to as an organism
• Can you think of some examples?
• What groups do they belong to?

4
What is an ecosystem?

• The living organisms and their non-living
  environment in a specific area is called an
  ecosystem
• This includes ABIOTIC and BIOTIC factors.
• What do you think ABIOTIC and BIOTIC means?

5
BIOTIC FACTORS

• bio life
• the biotic factors in an ecosystem are the living
  things
• Examples bacteria in the soil, insects, mammals
  etc

6
ABIOTIC FACTORS

• a not or without
• (in other words without life)
• all of the non-living components of an
  ecosystem
• Examples air, rocks, water, soil, climate, light
  availability topography etc.

7
What is a niche?

• All of the roles and relationships of an organism
  within its habitat
• This includes
• what the organism eats
• what eats the organism
• how it changes the environment etc.

8
What is a species?

• After the larger groups (domains, kingdoms, etc)
  are completely divided the smallest type of group
  is called a species
• Members of the same species group can mate and
  produce FERTILE offspring (fertile able to
  reproduce)

9
What does it mean to have fertile offspring?

• Fertile offspring can have babies of their own
• Example a pug and a Rottweiler could have
  fertile puppies (strange but true).therefore the
  pug and Rottweiller are the same species

10
What does it mean to have fertile offspring?

• Example A horse and a donkey can mate and
  produce an offspring known as a mule
• However, the mule is sterile (it can not
  reproduce)
• Therefore horse and donkeys belong to different

  Ligers and Tigons are sterile
• What does this say about lions and tigers as
  separate species?

12
What is a population?

• All of the members of the same species in a
  specific geographic area or time
• Which is bigger.a population or a species?

What is a community?

• The total of all the populations in an ecosystem
  the living part of the ecosystem
• What is a habitat?
• A specific place an organism lives is its
  habitat. Every habitat has specific biotic and
  abiotic factors organisms need to survive. The
  desert habitat has different factors than the
  grassland or the forest.
