Answer:
5.8 % of solar energy will be incorporated into gross primary production.
Explanation:
Ecological efficiency is defined as the amount of energy transfer from one trophic level to the next trophic level. In a ecosystem autotrphic organisms produce the organic energy from solar energy. According to the thermodynamics, there is no 100 % energy producer and consumer. That means some amount of energy is missing from one trophic level to the other.
In the ecosystem only 10% of energy is transferred from one trophic level to the next and production ratio is varying in different ecosystems. for example, grassland has higher gross production that an aquatic system.
