question 61

Multiple Choice

The following questions refer to the description below.
Plants are not able to move away from predators, so they have evolved chemical methods to protect themselves. Biologists have observed that caterpillars munching on a leaf can be attacked by certain species of wasps. These wasps lay their eggs inside the caterpillar's body, and when the eggs hatch, the larvae feed on its host from the inside.
-How do wasps find plants with caterpillars? You design an experiment in which one group of plants is torn/shredded by human fingers, another group of plants has leaves cut off with plant shears, a third group of plants has leaves stapled, and the fourth group of plants has leaves eaten by caterpillars. After several days of observation, only the plant with caterpillars has attracted wasps. The most likely conclusion is that

• A)plants take longer to release specific chemicals to attract wasps if leaves are damaged by means other than herbivory.
• B)plants "recruit" predatory wasps only when they are being eaten by a herbivore.
• C)plants damaged by shredding, cutting, or stapling produce chemical signals that likely repel wasps.
• D)wasps can detect the caterpillars by sight.
• E)wasps find the caterpillars by chance.
