Question
Explain the ecological efficiency.
✓
Answer
In each ecosystem, organisms obtain their food and convert the food into biomass for providing energy to next trophic level.
Ecological efficiencies are the percentage ratios between energy flow at different trophic levels of a food chain.
The unit of measurement of energy is Kcal/m2 /year. At the producer level, photosynthetic efficiency and net production efficiency are important. The efficiency with which a producer uses, incident solar radiation is measured by photosynthetic efficiency.
Photosynthetic efficiency $($ Producer level $)=$$\frac{\text { Gross Primary Productivity }}{\text { Incident Total Solar Radiation }}\times 100$
$\begin{array}{l}\text { Net production efficiency }= \frac{\text { Net Primary Productivity }}{\text { Gross Primary Productivity }} \times 100\end{array}$
Assimilatory efficiency (trophic levels) $=$ $\frac{\text { Net Primary Productivity }}{\text { Food Energy Ingested }} \times 100$
