Question

Draw a community.  It is ok if you need to make educated guesses about some of the direct interactions, but these should be plausible.

The following are minimum requirements for your community:

1) At least 5 different species, include common names and scientific names for each species.

2) For each species give a brief description of its role (i.e. what are its direct interactions)

2) At least 3 different types of direct interactions (e.g., mutualism, interference competition, commensalism etc).  All direct interactions shown with a solid arrow.

4) At least 3 different types of indirect interactions depicted (i.e. top down trophic cascade, bottom up trophic cascade, apparent competition, exploitative competition). All indirect interactions shown with a dashed arrow.

5) All arrows labeled with a + (positive), - (negative), and 0 (neutral) indication.

Do not include ALL possible interactions as it will be too cluttered. Just include the interactions necessary to fulfill the requirements 

Label the trophic level (e.g., primary producers, herbivore, secondary consumer, etc.
