For the following organisms, choose the correct order of increasing trophic level.
a. fungi, deer, wolf and grass
b. fungi, grass, wolf and deer
c. grass, deer, wolf and fungi
d. grass, fungi, wolf and deer

The correct answer should be C. Grass, deer, wolf, and fungi. That's because grass creates its own food since it's autotrophic, and it's then eaten by deer. The deer are eaten by wolves who wen dead are consumed by various types of fungi. The fungi are actually capable of decomposing them all but this is the correct order.
