1. What is symbiosis? What is a good example of a symbiotic relationship?
Symbiosis means living together, or same life. An example would be the clown fish and sea anemone. The fish lives in anemone and protects it, while the clown fish eats invertebrates that could harm the anemone and it also secretes ammonia that is used as nitrogen to fertilize it.
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.
These two make good examples because if there's too many wolves overpopulating Yellowstone the elk populations will drop. This limits the amount of food supplies for the predators, so their population drops as well, and vice versa. This also shows negative feedback loop because while one group benefits, the other doesn't.
4. What is the definition of a population?
A populations is made up of a many different individuals and all choices made by these individuals create a population with a specific behavior.
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?).
Kudzu was a plant released to the US in 1876. Over time, nothing adapted to eat Kudzu, and populations grew and expanded. A stink bug evolved to eat Kudzu, and this became a symbiotic relationship, because of how these organisms are interacting with each other. It's predation/parasitism, because only the stink bug gains the benefit from this relationship
