Study the diagram of a food chain shown below and use it to answer question 27 and 28.

P→Q→R→S→T

Which of the following statements best describes the organism designated R? It…

A. feeds on S.

B. is a primary consumer.

C. is a producer as well as a consumer.

D. is a secondary consumer.

QUICK ANSWER…

D

DETAILS…  

Organism R is at the third trophic level, it feeds on Q, and feed upon by S.

Now to the right option…

  1. Option A is incorrect; organism R feeds on Q and not S.
  2. Option B is also incorrect; organism R is not the primary consumer, the primary consumer is Q.
  3. No organism represented here serves the purpose of both consumer and producer, it’s either one is singularly a consumer, or singularly a producer. So, C is incorrect.
  4. Actually, D is very correct; R is at the center, the third trophic level, and clearly a secondary consumer.

QUICK TIPS…

You may please note that:

  • To refresh your memory, the five trophic levels are:
