Question

are my answers right?

After all reduced carbon has been consumed in your sample, you find that the number of viable cells increases when you expose the sample to light. This increase in cell number also requires the presence of CO2 Based on these data, which of the of following statements are true? 3. A The organisms growing are phototrophic. B. The organisms growing are chemotrophic. C The organisms growing are organotrophic. D. The organisms growing are autotrophic. E. The organisms growing are heterotrophic. 4. Common bacteria found in stagnant or polluted lakes are purple non-sulfur bacteria. They are photoorganoheterotrophs. This means they A They get energy from light. B. They get energy from chemical bonds They get electrons from inorganic sources They get electrons from organic sources. E. They get carbon from CO2

Explanation / Answer

3. The answer is A and D. The organisms growing are phototrophic and The organisms growing are autotropic. Because the need CO2 as well as the light.

The ogranotrophos depends on the organic carbons not on inorganic Carbon dioxide.

4.Photoorganoheterotrophs are heteroorganic phototrophs—that is they use light for energy, and they get energy from organic souces. So, the answers are A and C.
