Autotroph are producers. they produce their own light, water, and carbon dioxide. in the trophic levels, autotroph is considered the first level of the trophic levels otherwise known as producers. all food chains start with an autotroph. if there was an increase in autotroph, then there will be an increase in the animals that eat them. if there was a decrease in autotrophs, then the entire food chain will be affected. the animals depending on that certain type of autotroph will then have to find another food source, or they will eventually die of starvation
Answer:
The correct answer is- C) anaerobic chemoheterotroph
Explanation:
Chemoheterotrophs are the organisms that consume carbon compounds like carbohydrates, lipids, etc which are already synthesized by other organisms. Anaerobes are the organisms that live in an oxygen-deficient environment.
The human intestine is that part of the human body which is anaerobic in nature therefore in human intestine lots of anaerobic bacteria are present.
So as the hypothetical bacterium is present in the human intestine which has the anaerobic condition and derive nutrition from host intestinal contents therefore this bacteria must be an anaerobic chemoheterotroph.
