Answer 1

Answer:

secondary consumer will get only 200 joule and tertiary consumer will get 20 joule energy then only 18 joule energy is transferred to tertiary consumer.

Answer 2

Primary consumer: 2000  joule

Secondary consumer: 200  joule

Tertiary consumer: 20  joule

Explanation:

• According to the 10% law of energy transfer only 10% energy will be passed to the next trophic level and 90% energy will be lost as heat and incomplete digestion.  
• So according to this law out of 20,000 joules of energy of producers, only 2000(20,000*10/100=2000) will be transferred to primary consumers.
• Out of 2000, only 200 joules of energy will be transferred to secondary consumer and out of 200, only 20 joules of energy will be transferred to the tertiary consumer.
