Biome Interactions Instructions
Refer to the interactions map on the reverse of this page for numbers 1 - 7 below.
1. Write the name of your biome on the line at the top of the page.
2. Write one named example of each organism in the appropriate box. Names may be common names or scientific names, but they must
identify the species by name (i.e. “tree” is not a valid producer).
3. Which interaction between producers is represented by arrow “A”?
