Biology Essentials- Populations Guided Viewing Worksheet
1: What is symbiosis? What is a good example of a symbiotic relationship?
Symbiosis is the long term interaction between two organisms. An example would be a cat and a mouse.
2: List all of the types of interactions between two types of organisms in an ecosystem (give an
example of each).

3: Ecosystem Feedback Mechanisms
Explain how the Wolves/Elk populations in Yellowstone are a great example of a symbiotic
relationship and a negative feedback loop.
Wolves and elk show a negative feedback loop because the number of population in one will affect the other population also showing a symbiotic relationship.
4: What is the definition of a population?
Population is the count of how many there are of a species.
5: Discuss what is happening with the Kudzu Plant in the United States and explain how this is
an example of a symbiotic relationship (which?).
Because there were no kudzu consumers, the plant population grew enormously. When a bugged was able to evolve to eat this kind of plant, it started a predation symbiotic relationship as only the bug will benefit from it.
