The tertiary consumer will receive 500 calories.
<u>Explanation:</u>
Calories produced by the producer = 500,000
The flow of energy through different trophic levels is 10%
After producer comes the primary consumer followed by secondary consumer followed by tertiary consumer.
Energy reached to primary consumer =
= 50000 calories
Energy reached to secondary consumer =
= 5000 calories
Energy reached to tertiary consumer =
= 500 calories
Therefore, the tertiary consumer will receive 500 calories.
