A biologist began studying a population of bullfrogs. In 1998,
she found that most of the male frogs croaked, but some did
not. A bat species known to prey on male frogs migrated to
the area in 2005. The biologist returned to the area in 2008
and repeated population counts of male frogs. The table
shows her data.
