Question
A secondary consumer receives 200 kcal
from primary consumers. If the primary consumer originally received 2,000 kcal
from producers, what does this indicate about the efficiency of energy transfer from primary to secondary consumers?(1 point)
Responses
There is no energy loss because secondary consumers use all available energy.
There is no energy loss because secondary consumers use all available energy.
The energy transfer is 100%
, indicating that no energy or mass is lost between trophic levels.
The energy transfer is 100 percent , indicating that no energy or mass is lost between trophic levels.
The energy transfer is 10%
, with most energy being used by primary consumers for growth and maintenance.
The energy transfer is 10 percent , with most energy being used by primary consumers for growth and maintenance.
The energy transfer is 50%
, showing that half of the energy is used effectively for maintenance or lost as heat.

To find the energy transfer efficiency from primary consumers to secondary consumers, we need to compare the energy received by secondary consumers (200 kcal) to the energy initially received by primary consumers (2,000 kcal).
The efficiency can be calculated as follows:
\[
\text{Efficiency} = \left(\frac{\text{Energy received by secondary consumers}}{\text{Energy received by primary consumers}}\right) \times 100
\]
Now, substituting in the values:
\[
\text{Efficiency} = \left(\frac{200 \text{ kcal}}{2000 \text{ kcal}}\right) \times 100 = 10\%
\]
Thus, the correct response is:
**The energy transfer is 10%, with most energy being used by primary consumers for growth and maintenance.**
