CGCC Mortuary Science – Microbiology Practice Exam

Saprophytic bacteria are microorganisms that thrive on dead or decaying organic matter, playing a crucial role in the decomposition process. They break down complex organic substances into simpler compounds, recycling nutrients back into the ecosystem and contributing to soil fertility. This process of decomposition is essential for nutrient cycling and maintaining ecological balance.

Pathogenic bacteria, on the other hand, are harmful microorganisms that can cause disease in living organisms, and they do not primarily feed on decaying matter. Aerobic bacteria require oxygen for their metabolic processes; while some can be saprophytic, not all aerobic bacteria specifically feed on dead organic material. Symbiotic bacteria have a mutualistic relationship with other organisms, often providing benefits to their host rather than decomposing organic matter.

Understanding the role of saprophytic bacteria is vital in fields like mortuary science, where decomposition processes are directly linked to microbiological activity.
