supposed the primary producers in the energy pyramid shown contain 76500 kj of energy. how much would be available for the organisms on the tertiary level ?

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.
