If the energy transfer efficiencies of the ecosystem compone

If the energy transfer efficiencies of the ecosystem components are 1.3 % for plants, 13 % for herbivores, and 7 % for carnivores, what amount of energy in kcal/day do the carnivores receive if 1.7 x 106 kcal/year are available from the sun (Hint, use the diagram you produced in Problem 1)? 5.

Solution

energy received by plant= energy efficiency for plants* energy from sun

energy received by herbivores= energy efficiency for herbivores*energy received by plants

energy received by carnivores= energy efficiency for carnivoes*energy received by herbivores

=0.07*energy efficiency for herbivores*energy received by plants

= 0.07*0.13* energy efficiency for plants* energy from sun

= 0.07*0.13*0.013*1.7*10⁶  

= 201.11 Kcal/year

= 201.11/365 kcal/day

= 0.550 kcal/day
