Compare Energy Transfer between Defined Levels - Practice 2

Learn the skill

Transfer efficiency is energy entering the next defined trophic level divided by energy available at the source level, times 100. Use comparable areas and time intervals. Efficiencies vary; a 10% classroom example is not a universal constant.

Worked example

If 2000 kJ is available at one level and 300 kJ enters the next, the measured ratio is 15%.

Two bars on the same scale compare input 2000 kJ with output 300 kJ. Output is 15% of input. Use the boundaries specified in the worksheet; unused input is not destroyed.

Question 1 Fictional matched-area, matched-time record 6: 2000 kJ at the source level and 300 kJ entering the next. What is transfer efficiency as a percentage? Answer

Question 2 Fictional matched-area, matched-time record 7: 2000 kJ at the source level and 340 kJ entering the next. What is transfer efficiency as a percentage? Answer

Question 3 Fictional matched-area, matched-time record 8: 2000 kJ at the source level and 380 kJ entering the next. What is transfer efficiency as a percentage? Answer

Question 4 Fictional matched-area, matched-time record 9: 2000 kJ at the source level and 420 kJ entering the next. What is transfer efficiency as a percentage? Answer

Question 5 Fictional matched-area, matched-time record 10: 2000 kJ at the source level and 460 kJ entering the next. What is transfer efficiency as a percentage? Answer
