1. Ecological Relationships (Page #4) Interpret relationships, including predation, parasitism, commensalism, mutualism, and competition among organisms

3. Physical aspects (water, air, rocks, heat, light, altitude etc).
Chapter 16.1 Notes
Biotic Factors—
Living organisms
Abiotic Factors–
Non-living
Physical aspects (water, air, rocks, heat, light, altitude etc).

4. Quick Write:
Give an example of how abiotic factors determine the biotic factors that exist in an ecosystem? Explain.

5. Competition: Two species compete for the same resource.
Food, nesting sites, living space, light, mineral nutrients, water

6. Predation: + X
The act of one organism killing another for food (lions and zebras, spiders and flies, great grandma and chickens).

7. Symbiosis
A close, long-term ecological relationship between two or more species.
These relationships are essential to the balance of nature. They occur all around us and in us.
Come up with one example

8. Parasitism: + -
One organism feeds on and usually lives on or in another (Eventually harmful to host).

9. Mutualism: + + Beneficial to both species
Ants protect the aphids and the aphids feed the ants.

10. Commensalism + 0
Beneficial to one species but does not harm or benefit the other species.
While grazing, cattle dredge up the soil as nearby egrets feed on the newly exposed insects. The cattle are unaffected but the egrets get easier access to a food resource.

11. Bell-Ringer (Complete on Page 3)
Juvenile fish swim around jellyfish for a safe haven from potential predators. What type of ecological relationship is this?

12. Fictional Ecological Relationships #5
Fold paper into 3 sections.
Create Three Mini-Posters--one for each type of symbiosis (parasitism, mutualism, and commensalism).
For each poster, create two fictional organisms.
Each poster will illustrate how these two organisms live together.
Include title, 4 colors, sketch, and brief explanation of relationship.
