Four friends were arguing about the flow of energy between organisms in a food chain. They
wondered what happened to the stored energy in the grass plant as one organism eats another in a
food chain relationship. This is what they said:
Tatyana: "I think most of the plant's energy ended up in the fox.
Molly: "I think most of the plant's energy ended up in the snake.
Amos: "I think most of the plant's energy ended up in the grasshopper."
Ursula: "I think the amount of energy that was in the plant stayed the same when it passed through
the organism in the food chain."
Which student do you agree with the most?
Explain why you agree.

I would agree more with Amos' opinion, thinking that most of the plant's energy ends up in the grasshopper.

Explanation:

In food chains, the flow of energy that occurs from one organism to another, from the producer to the tertiary or quaternary consumer. The amount of energy that can be transferred from one level to another is only 10%, with herbivorous animals taking up more of the energy that a producer has.

According to this, it is logical to think like Amos, since the grasshopper -a primary or herbivorous consumer- will take advantage of more energy contained in the plant, with respect to the consumers of the higher levels.
