Question

to calculate the transfer efficiency through the food chain, the weight of the organism is multiplied by the percentage of energy passed on. in which food chain does 100 kg of primary producers yield 11 kg of apex predators? toggle between different food chains using the four buttons labelled a, b, c and d. follow the thick arrows from the primary producers to the apex predator. a) a b) d c) b

Explanation:

Step1: Calculate energy - transfer efficiency

The energy - transfer efficiency $E$ from primary producers to apex predators is calculated as $E=\frac{\text{mass of apex predators}}{\text{mass of primary producers}}\times100\%$. Given that the mass of primary producers is $100$ kg and the mass of apex predators is $11$ kg, then $E = \frac{11}{100}\times100\%=11\%$. We need to find the food - chain among A, B, C, and D that has this energy - transfer efficiency. Without the actual details of food - chains A, B, C, and D (their energy - transfer steps and efficiencies at each step), we assume we would calculate the overall efficiency for each food - chain by multiplying the efficiencies at each trophic level transfer. However, if we assume a simple linear energy - transfer model for each food - chain, we would need to check which one results in an overall $11\%$ transfer from primary producers to apex predators. Since we don't have the details of the food - chains A, B, C, and D, we can't perform the full calculation. But if we assume this is a multiple - choice question where we are given the options and we know the correct answer based on some pre - calculated values for each food - chain, we just need to pick the correct option.

Answer:

(No answer can be provided as the details of food - chains A, B, C, and D are not given)
