1.	What fraction of the assimilated energy is used in respiration by the herbivores?(a) ~ 10 per cent(b) ~ 60 per cent(c) ~ 30 per cent(d) ~ 80 per cent
Answer» Answer is : (c) ~ 30 per cent The energy assimilated by the herbivores is used in respiration and a fraction of unassimilated energy is transferred to decomposers (e.g. faecal matter). With increasing trophic levels, the respiration cost also increases sharply. On an average, producers consume about 20% of their gross productivity in respiration. The herbivores consume about 30% of assimilated energy in respiration. In carnivores, the proportion of assimilated energy consumed in respiration rises to about 60%.

Answer»

Answer is : (c) ~ 30 per cent

The energy assimilated by the herbivores is used in respiration and a fraction of unassimilated energy is transferred to decomposers (e.g. faecal matter). With increasing trophic levels, the respiration cost also increases sharply. On an average, producers consume about 20% of their gross productivity in respiration. The herbivores consume about 30% of assimilated energy in respiration. In carnivores, the proportion of assimilated energy consumed in respiration rises to about 60%.
