> 4. Describe how natural selection prompted the evolution of the Calvaria tree on the island of Mauritius.
Very bad question.
One researcher came to the conclusion that since there were so few trees, it must be that their seeds required passage through a dodo's gut to germinate, and dodos were extinct.
(Captain Obvious says that people cut down the mature trees, the lack of mature trees was due to lumberjacks, and the researcher had no idea what a young Calvaria tree looked like and thus did not recognize them when he saw them).
This researcher would have supposed that the Calvaria had evolved in response to the bird eating the seeds, to have seeds with a tougher endocarp to withstand the bird digestive system.

> 5. How does the extinction of the dodo bird impact the survival of the Calvaria?
It didn't. Bad question. But if the Calvaria tree seeds really did require passage through the digestive system of a dodo, then extinction of the dodo would mean that no seeds would germinate, which would mean eventual extinction for the Calvaria tree.

> 6. How is the survival of some plant species tied to periodic fires?
a) Some seed pods or cones do not open unless exposed to a fire.
b) Fire removes competitors for sunlight, space, water, nutrients.
