प्रश्न
How much of the net primary productively of a terrestrial ecosystem is eaten and digested by herbivores?
विकल्प
1%
10%
40%
90%
उत्तर
10%
Explanation:
Only 10% of herbivore output is used for increasing productivity of the next tropic level, according to the 10% low of energy flow in a chain, while the remaining 90% is eaten and used up in processes such as breathing, body cleanliness, and after activities.
