3-24-09 QUIZ TOMORROW!!
We’re going to have a quiz over the five major animal interactions:
Predation – a relationship in which one animal hunts and kills another for food.
Competition – when two organisms compete for the same resources (like food, water, shelter, etc.)
Mutualism – a relationship in which both animals benefit (like a bee getting nectar and a flower getting pollinated.
Commensalism – a relationship in which one animal benefits and nothing happens to the other (like a clownfish living in sea anemone
Parasitism – a relationship in which one animal benefits and the other is hurt or killed (like a leech and a human).
Also…make sure you know how to read animal population graphs!!
