Question

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

Answer 1

c. grass → deer → wolf → fungi

Reason: grass are primary producers, deer are primary consumers (herbivores), wolves are higher-level carnivores, and fungi are decomposers that break down dead organisms (functionally placed after the consumers).
