In a food chain, if 10000 Joules of energy is available to the producer, how much energy will be available to the secondary consumer to transfer it to the tertiary consumer?
(i) Energy available to producers = 10,000 Joules. Energy transfer to producer = 1% of 10,000 Joules = 100 Joules. (ii) According to Ten per cent law, Energy transfer to primary consumer = 10100 × 100 = 10 Joules. (iii) Energy transfer to secondary consumer = 10100 × 10 = 1 Joule (iv) Energy transfer to tertiary consumer = 10100 × 1 = 0.1 Joule
