D
Obligate aerobes
Verified step by step guidance1
Understand the concept of fermentation: Fermentation is a metabolic process that allows cells to produce energy (ATP) in the absence of oxygen. It is an anaerobic process, meaning it does not require oxygen.
Identify the types of organisms that rely on fermentation: Organisms that thrive in environments without oxygen, such as anaerobic bacteria, often use fermentation as their primary method of energy production.
Eliminate options that do not fit: Marine algae and photosynthetic plants primarily rely on photosynthesis, which requires light and often oxygen. Obligate aerobes require oxygen for survival and energy production, so they do not rely on fermentation.
Focus on anaerobic bacteria: Anaerobic bacteria are organisms that live in oxygen-free environments and use fermentation to generate energy. This aligns with the definition of fermentation.
Conclude that anaerobic bacteria are the most common organisms to use fermentation, as they are specifically adapted to environments where oxygen is absent.
