An increase in pesticide use has resulted in a decrease in the local blue jay population. what is the best explanation for the decreased blue jay population? a) blue jay food supply increased. b) blue jay food supply decreased. c) many blue jays moved into the area. d) infection with the pesticide destroyed most of the blue jay population.

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.

hey, i believe your answer would be d. sugar ribose and the base uracil. i believe this is the answer, because rna consists of sugar ribose, adenine, guanine, cytosine, and uracil.

your first option is incorrect, because that's dna. where it consists of sugar deoxyribose, adenine, guanine, cytosine and thymine.

your second option is also incorrect, this is because sugar deoxyribose is in dna, and uracil is in rna. these two do not make sense together.

your third option being incorrect, because sugar ribose is in rna, but not the base of thymine. rna consists of uracil, not thymine.

lastly your fourth option being correct! this answer is correct, because both sugar ribose, and the base uracil are in rna! ~

answer is d. sugar ribose and the base uracil.
