1. Ecological Succession

2. Biotic Factors
Living part of the environment
Tree, plants
animals

3. Abiotic Factors
Nonliving parts of the environment
Water
Rock
sun

4. Habitat and Niche
Habitat – area where an organism lives (the organism’s “address”)
Niche – the physical conditions that help the organism to survive (the organism’s “occupation”)
Type of food organism eats
How it gets food
Which other species eats the organism
When and how the organism reproduces

5. Competitive Exclusion Principle
No two species can occupy the same niche in the same habitat at the same time.
Example:
Cape May Warbler feeds at the tips of branches near the top of the spruce tree
Bay-Breasted Warbler feeds in the middle part of the spruce tree
Yellow Rumped Warbler feeds in the lower part of the tree and at the bases of the middle branches

6. Predation – interaction in which one organism captures and feeds on another organism
Symbiosis – relationship where 2 species live closely together

7. Mutualism Both species benefit from the relaitonship
As far as is known, the fish is able to produce a special mucus that causes the anemone not to release its stings. It is also believed that the movements of the fish inform the anemone of its identity. In return for the anemone's protection, the fish brings scraps to it, and lures larger fish into the anemone's tentacles.

8. Commensalism
One organism is benefited and the other is not helped nor harmed
Barnacles on a whale do not hurt the whale nor help it, but they benefit from the whale because as a whale swims, the water carries food particles to them

9. Parasitism
One organism is benefited and the other is harmed

10. Ecological Succession
Primary – occurs where no soil exists, only ash and rock
1st species to populate
Often lichens (fungus and algae)
When they die they create organic material to make soil for other plants to grow

11. Secondary Succession
Occurs when land is cleared and plowed for farming or after a forest fire
Plants start to grow

12. Climax Community
Full forest – animals and plants living together
