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.
It may have been difficult to discover pond water organisms from pond water sample under the microscope comparing to cheek cell sample and leaf sample because of the large area and involved and the cheek cell and leaf sample being a living tissue.
<h3>What is a Microscope?</h3>
This is referred to as a laboratory equipment which is used in the enlargement of objects and cells and ensures that very small organisms can be seen and observed.
Living cells such as cheek cell and leaf sample are what the organisms mostly feed on which is why it is easy to see and observe them when compared to pond water.
Pond water also has a very large surface area and the sample gotten may not possess any organism which is why it may be difficult and is therefore the reason why it was chosen as the correct choice.

<span>The two most common ways are the use of a water restrictor in the shower head, most of the heads in the U.S.A are equipped with a water restrictor. Secondly, the commode water tanks have been made smaller using less water per flush. Some conservation of water may be gained by using "instant" water heaters in the shower/bath and basin rather than a hot water tank type heater. Locating an instant water heater near the output of the water reduces the need to let the water run until it becomes hot at the output. </span>I hope that this is the answer that you were looking for and it has helped you.
