Answer

Net secondary production is 20J. Production efficiency is 40%.

Work Step by Step

The net secondary production is what's left from the noted functions. $100J-(30J+50J)=20J$ Production efficiency = $\frac{Net \space secondary \space production\times100%}{Assimilation \space of primary \space production}$ Production efficiency = $\frac{20\times100}{30+20}$ Production efficiency = 40%
