Electrolysis Practice Exam

What do you call bacteria that decompose dead or decaying matter?

1. Pathogens

2. Saprophytes

3. Decomposers

4. Photosynthetic bacteria

The correct answer is: Saprophytes

Bacteria that decompose dead or decaying matter are known as saprophytes. These microorganisms play a crucial role in the ecosystem by breaking down organic material, which helps recycle nutrients back into the soil. This decomposition process is essential for the health of ecosystems, as it ensures that essential nutrients are not locked away in dead organisms but can instead be made available for use by plants and other organisms. While the term "decomposers" also refers to organisms that break down organic matter, saprophytes are a specific group that includes certain bacteria, fungi, and other microorganisms. This distinction highlights their specific role in the breakdown of organic materials. Pathogens, on the other hand, are organisms that cause disease and are not primarily involved in decomposition. Photosynthetic bacteria, while important in specific ecological processes, focus on converting light energy into chemical energy, rather than decomposing matter.
