Carbon Dioxide (or CO2) is produced by the lungs I think because when you inhale, you breathe in oxygen, then you exhale the carbon dioxide in the lungs. That's actually 3 and 4.

Explanation:
The sugar produced is Glucose. (2)
10 percent of energy is passed from one tropic level to the next. While the other 90 percent of energy is lost to heat.
B. Salmonella
Isotonic solutions will have the same or a very similar concentration when compared to the cell or microbe within it. Based on the chart above, Salmonella has a salt concentration as a percentage of volume of 0.9. If the salt concentration of a solution is 1% then 0.9 is the closest compared to the others. Paramecium will be hypotonic while Amoeba and Plankton would be hypertonic in this solution.
