Correct Answer(b) Grass, Goat, and Human


The grass is a producer, a goat is a primary consumer (herbivore), and a human is a secondary consumer (omnivore).

A food chain comprises a producer, primary consumer, secondary consumer, and decomposer, where one organism in the chain is the energy and nutrient source for another organism.

  • Grass, wheat, and mango are producers.
  • Goats, cows, and elephants are the primary consumers.  
  • Grass is the producer, while fish and goats are the primary consumers, so they cannot constitute a food chain.
