प्रश्न
How much energy will be available to hawks in the food chain comprising hawk, snake, paddy and mice, if 10,000 J of energy is available to paddy from the sun?
उत्तर
Ten percent of the energy will be available to hawks.
In this food chain, the energy transfer will take place as follows.
- Paddy → Mice→ Snakes →Hawks
10 J 1 J 0.1 J - Paddy → 1% energy trap → 100 J of Energy
- 10% Law of Energy
