Arrange the given organisms in the food chain starting from lower to higher trophic level?

(A) Lion
(B) Cow
(C) Grass
(D) Wolf

Choose the correct answer from the options given below:

(C), (B), (D), (A)

The correct answer is Option (4) → (C), (B), (D), (A) 

To arrange the organisms in the food chain starting from the lower to the higher trophic level, we need to identify the producer and the consumers in order of their feeding relationships.

• Grass (C) is a producer (autotroph) and forms the base of the food chain (trophic level 1).
• Cow (B) is a herbivore that feeds on grass (primary consumer, trophic level 2).
• Wolf (D) is a carnivore that feeds on herbivores like cows (secondary consumer, trophic level 3).
• Lion (A) is a top carnivore that may feed on wolves or other carnivores (tertiary consumer, trophic level 4).

So, the correct order from lower to higher trophic level is: Grass (C) → Cow (B) → Wolf (D) → Lion (A)
