Lactic acid is produced after we worked our heart strenuously, which alert our body to tense up the muscle end slow down any activity that we currently doing to prevent potential organ failure
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.
