10. Two distinct bird species occupy an island. Species A has a short, broad beak and eats large seeds. Species B has a short, narrow beak and eats small seeds. If the large seed crop is greatly reduced one year, while the small seed crop remains unchanged, which of the following is likely to occur among individuals of the two species?
11. Two species of bivalve mollusk occupy the Scottish coast. Species A is found above high tide mark while Species B is found in the intertidal zone.

13. Two species of bivalve mollusk occupy the Scottish coast. Species A is found above high tide mark while Species B is found in the intertidal zone. If Species B is experimentally removed from the study site, Species A colonizes the area previously occupied by Species B.
