• With the organisms given in the question, following will be the food chain in action:
• Weeds → Tadpoles → Water beetles → Fish

(i) Predators in this food chain are water beetles and fish. Water beetles eat tadpoles i.e. they prey on tadpoles. Fish eats water beetles i.e. it preys on water beetles
(ii) Prey in this food chain are tadpoles and water beetles. Tadpoles are eaten by water beetles and water beetles are eaten by fish.
