100J
10J​

Answer 1

Answer:

Explanation:According to the 10 percent law, only 10% of the energy is transferred to each trophic level from its lower trophic level. If 10,000 joules of energy is available to the producer, then only 1000 joules of energy will be available to the primary consumer and only 100 joules of energy will be available to the secondary consumer. The energy available with the tertiary consumer will be 10 joules of energy.  

Answer 2

Answer:

1000 KJ

Explanation:

the given food chain fourth trophic level is occupied by snakes. The available energy is 10 kJ at snakes, so at the producer level energy should be 1000 kJ. Grasshopper will get 100kJ energy as per 10 % law and frog will get 10 kJ and then snake will get 10kJ energy which is 10 % of 100 kJ.Read more on Sarthaks.com - https://www.sarthaks.com/942738/given-chain-suppose-amount-energy-fourth-trophic-level-energy-available-producer-level
