Answer:
76.5Kj
Explanation:
A food chain consists of different trophic levels of organisms ranging from the PRODUCERS to the TERTIARY CONSUMERS. According to the pyramid of energy, only about 10% of energy is available for use for the next trophic level as majority of the energy (about 90%) is lost as heat.
Hence, if the primary producers in the energy pyramid contains 76500kJ of energy, the following energy would be available for each trophic level.
Primary producers: 76500kJ
- 10% of energy will be available to the primary consumer = 10/100 × 76500 = 7650kJ
- 10% of energy (7650kJ) will be available to the secondary consumer = 10/100 × 7650 = 765kJ
- 10% of energy (765kJ) will be available to the tertiary consumer = 10/100 × 765 = 76.5kJ
Hence, 76.5kJ of energy will be available for organisms at the tertiary level.
