  1. Earthworms
  2. Jellyfish
  3. Millipedes
  4. Seahorses
  5. Woodlice Select the correct answer using the code given below.

C.1, 3 and 5 only
B.2, 3, 4 and 5 only
D.1, 2, 3, 4 and 5
A.1, 2 and 4 only

Correct Answer: Option C

Detritivores are heterotrophs that obtain nutrients by consuming detritus (decomposing organic matter).

Examples of detritivores include:

  • Earthworms
  • Millipedes
  • Woodlice

Seahorses are secondary consumers, primarily feeding on plankton, small fish, and small crustaceans.

Jellyfish are also secondary consumers, feeding on other marine organisms.

Therefore:

  • Statement 1 is correct.
  • Statement 2 is not correct.
  • Statement 3 is correct.
  • Statement 4 is not correct.
  • Statement 5 is correct.

Hence, option (c) is the correct answer.
