An organism gets carbon by using carbon dioxide in the atmosphere to make sugar molecules. this organism is a:
a. higher-level consumer.
b. primary consumer.
c. producer.
d. decomposer.
e. none of the above.

The answer is producer

Explanation:

Producers are organisms which mainly include green plants, possessing the green coloured pigment named CHLOROPHYLL. Chlorophyll helps it to

- trap energy from the sun in the presence of carbon dioxide (CO2) in the atmosphere and water to make sugar molecules (glucose).

The process is known as PHOTOSYNTHESIS, and is shown below

6CO2 + 6H2O ---> C6H12O6 + 6O2 + Energy.

From the equation, carbon is used in form of carbon dioxide to produce sugar (glucose) molecules

both anaerobic and aerobic respiration use glucose (or other carbohydrates), proteins and lipids to produce atp and nadh. cell uses those energy molecules, obtained from food and   breaks them down during the chemical reactions of respiration. in anaerobic respiration, nadh is regenerated to nad+ by enzymes lactate dehydrogenase (lactate is produced, e.g. in muscle cells) or by alcohol dehydrogenase where ethanol is produced (alcohol fermentation), while in aerobic respiration, electrons from nadh are deposited in the mitochondria to regenerate nad+ (electron transport chain. anaerobic respiration produces 2 atp per molecule of glucose compared to aerobic respiration where about 38 atp molecules are produced.
