answer the following questions about Variable modes of facilitation in the upper intertidal: goose barnacles and mussels

I’m studying for my Biology class and don’t understand how to answer this. Can you help me study?

First read the article then answer the following question

1. Explain why the relationship between Capitulum mitella and Septifer virgatus is characterized as facilitation. Find colored photos of these organisms to share and be able to provide basic information about these species.

2. What is the hypothesis being tested or the goals of the experiment? Explain why this study falls under the field of ecology by identifying how this experiment will help to explain the distribution or abundance of species. How will this study improve understanding of community dynamics?

3. Briefly describe the methods used with a diagram. Include the sample sizes and locations/treatments.

4 .Summarize the main results.

5. Summarize the main conclusions of the discussion section in your own words.
