It flows through the consumers (first level second level so forth). However, at each level, it loses 90 percent of the energy as heat. So at each level, each consumer will only get 10 percent of the energy.

Smoking have life-threatening effects on a smoker's lungs. A smoker is at a high risk of lung cancer and chronic obstructive pulmonary disease. In order for a coach to explain the destructive effects of smoking on the performance of the athletes, it is best to show a diagram of the flow of the oxygen-rich blood in a non-smoker's body and then the flow of blood with less-oxygen in smoker's body. This will show the difference between the two situations clearly, and show how the airway resistance effects the performance of a person.
Hence, the answer is 'option C - Diagram the flow of oxygen-rich blood in non-smoker's body and the, diagram of flow of blood with less oxygen in smoker's body'.

A DNA molecule consists of two strands of nucleotides twisted together to form a double helix. The sugar-phosphate backbone is found on the outside of this helix and the bases are found braching towards the middle. Hydrogen bonds join the thenitrogenous bases and hold the two strands together.
Therefore your answer is sugar and phosphate.
