Question
A) 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)
The energy transfer is 50%, showing that half of the energy is used effectively for maintenance or
lost as heat.
The energy transfer is 100%, 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.
There is no energy loss because secondary consumers use all available energy.

The correct interpretation of the energy transfer from primary consumers to secondary consumers is:
**The energy transfer is 10%, with most energy being used by primary consumers for growth and maintenance.**
This is because the primary consumer received 2,000 kcal and transferred only 200 kcal to the secondary consumer, indicating that only 10% of the energy from the primary consumer is passed on to the secondary consumer. This is consistent with the typical efficiency of energy transfer between trophic levels, which is generally around 10%.
**The energy transfer is 10%, with most energy being used by primary consumers for growth and maintenance.**
This is because the primary consumer received 2,000 kcal and transferred only 200 kcal to the secondary consumer, indicating that only 10% of the energy from the primary consumer is passed on to the secondary consumer.
