question 21

Multiple Choice

Most bats emit high-frequency and high-intensity sounds, and by their returning echoes, create an image about their surroundings. Under selective pressure from this prey-location system, certain moths (which are bats' prey) have evolved simple ears that are particularly sensitive to frequencies used by bats. When they hear the bats, they drop to the ground. The bats, in turn, have switched their sound frequency away from the moth's sensitivity range. What do we call this type of adaptation in both bats and moths?

• A)trophic interaction
• B)coevolution
• C)neutral interaction
• D)evolution
