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
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 50%
, showing that half of the energy is used effectively for maintenance or lost as heat.
The energy transfer is 50 percent , showing that half of the energy is used effectively for maintenance or lost as heat.
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.
There is no energy loss because secondary consumers use all available energy.

To determine the efficiency of energy transfer from primary consumers to secondary consumers, we can use the given information:
- The primary consumer received 2,000 kcal from producers.
- The secondary consumer received 200 kcal from primary consumers.
To calculate the efficiency of energy transfer from primary to secondary consumers, we divide the energy received by the secondary consumer by the energy received by the primary consumer, and then multiply by 100 to get a percentage:
\[
\text{Efficiency} = \left( \frac{\text{Energy received by secondary consumers}}{\text{Energy received by primary consumers}} \right) \times 100
\]
\[
\text{Efficiency} = \left( \frac{200 \text{ kcal}}{2000 \text{ kcal}} \right) \times 100 = 10\%
\]
This indicates that the energy transfer from primary consumers to secondary consumers is 10%.
So, the correct response is:
**The energy transfer is 10%, with most energy being used by primary consumers for growth and maintenance.**
- The primary consumer received 2,000 kcal from producers.
- The secondary consumer received 200 kcal from primary consumers.
To calculate the efficiency of energy transfer from primary to secondary consumers, we divide the energy received by the secondary consumer by the energy received by the primary consumer, and then multiply by 100 to get a percentage:
\[
\text{Efficiency} = \left( \frac{\text{Energy received by secondary consumers}}{\text{Energy received by primary consumers}} \right) \times 100
\]
\[
\text{Efficiency} = \left( \frac{200 \text{ kcal}}{2000 \text{ kcal}} \right) \times 100 = 10\%
\]
This indicates that the energy transfer from primary consumers to secondary consumers is 10%.
So, the correct response is:
**The energy transfer is 10%, with most energy being used by primary consumers for growth and maintenance.**
