Answer

Brief Explanations:

When a plant - disease kills all the fruit, it creates a selective pressure. Flock X may try to eat other foods as their main food source is gone. Migration in search of fruit is also a possible response. If they can't adapt, their numbers could decrease. Flocks Y and Z may benefit if they can better utilize alternative food sources. Mutation is a random process and organisms do not 'try' to mutate.

Answer:

Flock X may try to eat other foods. Flock X could migrate in search of fruit. Flock X could slowly decrease in number. Flocks Y and Z could benefit and increase.
