Answer:

Among the given options, the Grass, Goat, and humans form a food chain. Option (2) is correct.

Explanation:

• The movement of nutrients and energy in the ecosystem is described as a food chain.
• Plants are at the basic level of a food chain.

In a food chain at the basic level, green plants are there. The second level consists of the herbivores like goats or cows. The third level consists of organisms that eat these herbivores. This level includes humans, dogs, crows, and various other omnivores.
