Answer 1

b would be the right answer

Answer 2

The right answer is B) Blue jay food supply decreased.

Blue Jay feed mainly on plants, such as wild fruits, acorns, hazelnuts, beechnuts, corn and other cereals, and all kinds of insects. They can thus contribute largely to the fight against the caterpillar.

The increase in insecticides will deprive them of one of these food sources that are insects. which causes a decrease in their food supplies.
