When hunting disrupts balance in the food chain by removing all owls, there will be no predators on snakes, leading to their increase in numbers. Considering the scenario where the number of lost owls (4) is replaced by snakes, compute for energy units following the table in no. 1 (Sun + E = 6) and answer the following questions: In comparison with the natural food chain, which component received less energy in this unbalanced food chain? What is the reason for the above? What might be the consequences of the above? What is needed to recover balance in the food chain? How can this be achieved in this specific situation?
