Final answer:
The impact of tadpole and bird extinction on the given food chain explained.
Explanation:
Food Chain Impact Analysis:
- If all the tadpoles died, it would disrupt the food chain causing a decrease in eel population, potentially leading to an increase in pondweed due to reduced predation pressure on them by tadpole eels.
- If all the birds died, it could result in a surge of tadpole eel population due to the removal of a major predator, which might lead to a decline in pondweed as eel numbers increase.
