Using the data in this table, calculate the: Net production efficiency of insects.

• A. 19%
• B. 73%
• C. 27%

Answer: (C)

Verified step by step guidance

1. Understand the concept of Net Production Efficiency (NPE), which is the ratio of net production to the assimilated energy. It is expressed as a percentage.
2. Identify the relevant data from the table: Gross insect production (assimilated) is 520 kcal/(m²*yr) and Net insect production is 102 kcal/(m²*yr).
3. Use the formula for Net Production Efficiency: \( \text{NPE} = \left( \frac{\text{Net insect production}}{\text{Gross insect production (assimilated)}} \right) \times 100 \).
4. Substitute the values from the table into the formula: \( \text{NPE} = \left( \frac{102}{520} \right) \times 100 \).
5. Calculate the result to find the Net Production Efficiency of insects, which will give you the percentage value.
