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.
Scientists study both the flatworm Planaria and the roundworm Caenorhabditis elegans in laboratories, using them as test subjects, and while they may seem similar, they have some distinct internal and external differences. Flatworms (phylum Platyhelminthes) and roundworms (phylum Nematoda) differ in shape, means of locomotion, how their digestive systems function, and in the ways they are harmful to human beings. While both species are called worms, they are not closely related.
