Question

Quizplus · Accepted Answer

According to the 10% rule of energy transfer in ecosystems, only about 10% of the energy is passed on to the next trophic level. Therefore, if crickets receive 1,000 kilocalories from the grass, they pass on approximately 100 kilocalories to the birds, and the birds would have about 10 kilocalories.
