a food web diagram showing cornstalks with two arrows pointing away from it. one of the arrows points to the letter x and the other arrow points to a grasshopper. there are two arrows pointing away from the grasshopper. one is pointing to a baby sparrow and the other to the letter y. there is an arrow pointing away from the baby sparrow to a snake and an arrow pointing away from the letter x to the snake.

if a certain organism is a primary consumer, what best explains its position in the food web?

x, because organism x has the same role as the grasshopper
y, because organism y has the same role as grasshopper
x, because organism x has the same role as the baby sparrow
y, because organism y has the same role as the baby sparrow
