The table below shows information about how energy is transferred in a bird (goose) and a fish (trout).
| Animal | Percentage of energy in food absorbed | Percentage of absorbed energy released by respiration | Percentage of absorbed energy assimilated into biomass |
|---|---|---|---|
| Goose (bird) | 35.0% | 93.0% | 7.0% |
| Trout (fish) | 82.0% | 38.0% | 62.0% |
Suggest why the goose absorbs a lower percentage of energy from the food it eats than the trout.
Suggest why the goose releases a much higher percentage of the absorbed energy by respiration than the trout.
The data suggests that trout production is highly energy-efficient compared to farming geese. Using your knowledge of energy transfer, suggest two ways in which the productivity of geese could be improved by a farmer, explaining the biological reason for each.
