These can be animal-animal, animal-fungal, plant-fungal, plant-animal, bacteria-animal....the sky is the limit! For this particular forum, you'll be able to see other classmates postings even before you post your own. This is so you can present an example that's different from what's already been discussed. Remember that mutualistic interactions are associations that benefit both parties -- so your response should clearly indicate the role each partner plays. Let us know where these organisms are found, what kind of habitat they live in, and any other interesting , pertinent information. Also, please comment on how natural selection likely played a role in the development of your example. You can use your imagination a bit here -- I'd just like to see you connect the ideas.
