Answer to Question 1

A

Answer to Question 2

Answers will vary:
Mutualism should be an example where both organisms benefit, such lichen, clownfish and sea anemones, or bison and prairie dogs. Parasitism should focus on one organism benefiting at the expense of the other, such as mistletoe or lice. Commensalism should include an example where one benefits and the other gains no benefit, such as an ephiphytic plant or animals attaching to others for transportation. Amensalism should look at where one organism is harmed and the other does not benefit, e.g. allelopathy.
