Which statement describes the role of the organism indicated by the blue arrow in the food web? A secondary consumer that obtains its energy from the consumption of plants
A primary producer that recycles organic molecules from sunlight
A primary decomposer that recycles organic molecules by breaking them down
A primary consumer that obtains its energy from the consumption of plants

A primary consumer that obtains its energy from the consumption of plants

Explanation:

Organisms that eat the producers are the primary consumers. In this case, the producer is the grass, which is then eaten by the primary consumer, the meadow vole.

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.

this is math not biology xd
