Debate time! Each team picks a representative. Your question is 'should parasites be considered important parts of ecosystems, or should we try to eliminate them whenever possible?'. You have 30 seconds to argue your case.

State one similarity and one difference between a predator-prey relationship and a parasitic relationship.

Why does the Lynx population line seem to imitate the Hare population line?

Epiphytes are plants which grow high in the branches of other trees. They obtain sufficient sunlight to photosynthesise, collect water from moist air, and use decaying leaf litter as nutrients. The tree is not harmed. What rel is this? Why?

Explain what a mutualistic relationship is as though you're talking to a first grader.

Ocean acidification is leading to a mass decrease in coral populations. Corals provide food and shelter for fish and other marine life. If corals were to go extinct, how would this impact the fish and ecosystem as a whole?

Come up to the whiteboard, I will write a term above your head. Your team can give you hints but cannot say the word itself. You have one minute to guess the term correctly.

Using the graph above, predict when the Hare population is likely to peak next.

Predict what might happen if the Lynx population were to entirely disappear from the ecosystem.

Time for Charades! Come to the front and act out the type of symbiotic relationship I give you. Your team has one minute to guess, you cannot speak.

Spelling bee! You must spell a word of my choosing. Write your answer on the whiteboard.
