In a food chain, energy flows
Open in App
Solution
The correct option is A From low to high level
In a food chain, energy enters through producers. Producers such as plants synthesize their own food in presence of sunlight. They convert solar energy into chemical energy. From producers, the energy flows to the primary consumers to the secondary consumers to the tertiary consumer. Hence, the energy flow in a food chain is always from low to high level. During energy transfer, only 10% of energy is transferred from one trophic level to another trophic level.Thus, the correct answer is 'From low to high level.'
