Answer :
When we examine the transfer of energy from one trophic level to the next in an ecosystem, we're typically talking about ecological efficiency. This refers to the amount of energy that is passed on from organisms at one trophic level to those at the next trophic level.
In the context of secondary production, we're particularly interested in the efficiency of energy transfer from primary producers (like plants) to primary consumers (herbivores), which are then the food resource to secondary consumers.
As per the standard principles of ecology, the average energy transfer efficiency from one trophic level to the next is roughly 10%. However, in the context of this specific question and the answer choices provided, we'll choose the value that best represents the typical efficiency threshold for the energy transfer to secondary consumers.
While the most accurate ecological figure is around 10%, this is not listed among the provided answer options. Instead, we select the next closest value, which is 5 percent. Therefore, the typical efficiency threshold for secondary production is about 5 percent. The correct answer is:
B. about 5 percent
