 DO NOW- have current event out on
                your desk

1. What is the primary source of energy
on the planet?
2. What is a “baby” frog called?
3. What process do autotrophs carry
out in order to make glucose and
oxygen?
                 GOAL

To define ecological vocabulary words
To distinguish between several biomes
To differentiate between the ecological
relationships found in nature
      Ecology Video Questions

1.   What is a community?
2.   What is a population?
3.   What is a habitat?
4.   What is a niche?

    Ecological Relationships

Ecology   Study of the relationships
          between living things and the
          environment
      Ecological Relationships

Biosphere   Thin zone of life above and
            below earth’s surface
        Ecological Relationships

Biome        Portion of biosphere with
             specific temperature and
             amount of rainfall
             – Tundra
             – Rainforest
      Ecological Relationships

Ecosystem   Living and nonliving things in
            an environment
            Ex:
            –   Ocean
            –   Forest
            –   River
            –   Lake
       Ecological Relationships

Community   All the living organisms that
            share the same environment
            Ex:
            – A community of trees, flowers and
              reptiles
        Ecological Relationships

Population   One type of species living in an
             area
             Ex:
             – Population of Zebras
          Ecological Relationships

Habitat        An organism’s “special place”
               or home in an ecosystem
               Ex:
               – Swallow (bird) habitat = tree
        Ecological Relationships

Niche        An organism’s specialized job
             within an ecosystem
             Ex:
             – Tiger= carnivore- eats other
               animals (meat)
          Ecological Relationships

Abiotic        Non living things in the
Factors        environment
          Ecological Relationships

Biotic         Living things in the environment
