Question: 338

8. A rattlesnake would be classified as a

A. tertiary consumer and a heterotroph
B. secondary consumer and an autotroph
C. producer and an autotroph
D. producer and a heterotroph
E. primary consumer and a heterotroph

Correct Answer: A


A Rattlesnakes are clearly heterotrophs (only photosynthetic organisms are autotrophs), so we can eliminate choices B and C. Rattlesnakes are carnivores, not producers (D is wrong) or primary consumers (herbivores, so E is wrong).
