In a community, what are some ways 2 species can interact with each other? Write them down on your paper.

2. Announcements Unit 5 Evolution Retakes: (THIS IS THE LAST WEEK)
M- until 3:30
Tuesday- until 4
Thursday- until 4:30
Friday- morning

3. Interactions Fish are friends, not food!
Interaction: A situation where two species affect each other

4. Background Terms- Community Level

5. Autotroph vs. Heterotroph
Troph = energy
Autotroph = organisms that make their own food

9. Key Terms
Parasite: an organism that lives in or on another organism (its host) and benefits by getting nutrients at the host's expense.

10. Interaction Skits There are 5 main ways that 2 species can interact.
Each group will have 10 minutes to prepare a skit showing how the two species interact, and then the class will have to guess HOW they are interacting.
The group will then go over the vocabulary term associated with their interaction.
Guidelines:
Each person MUST play a role in the skit
You cannot say the word of your interaction
Each person MUST be able to explain your term

11. Identify the following!
