Prokaryotes that break down dead organisms in an ecosystem are called

The correct answer is -

Decomposers.

Prokaryotes are those organisms that are devoid of nucleus and membrane bound subcellular compartments (called cell organelles).

They primarily include bacteria, which act as decomposers, by breaking the organic compounds of different life forms such as plants and animals into simpler forms (which are vital nutrients such as carbon, nitrogen, phosphorous) that are returned back to the environment.

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.
