Answer:
I can't insert a food chain here, but the reason why tuna may have more mercury contamination than salmon or trout is because it is higher up in trophic structure. Why is this significant? It's because of a phenomenon known as biological magnification, in which toxins accumulate the most at higher trophic levels.
It depends on the question
Answer:
In the electron transport chain, electrons are passed from one molecule to another, and energy released in these electron transfers is used to form an electrochemical gradient. In chemiosmosis, the energy stored in the gradient is used to make ATP.
