Which type of prokaryotic organisms are primarily responsible for breaking down the remains of dead organic matter in the environment?

• A. Decomposers
• B. Symbionts
• C. Producers
• D. Pathogens

Answer: (A)

Verified step by step guidance

1. Understand the role of decomposers in an ecosystem: Decomposers are organisms that break down dead or decaying organisms, and in doing so, they carry out the natural process of decomposition.
2. Identify the types of organisms that can act as decomposers: In the context of prokaryotic organisms, bacteria are the primary decomposers. They break down complex organic materials into simpler substances.
3. Differentiate between the given options: Symbionts are organisms that live in close association with another species, often benefiting both. Producers are organisms, like plants and some bacteria, that produce their own food through photosynthesis or chemosynthesis. Pathogens are organisms that cause disease.
4. Focus on the function of decomposers: Decomposers play a crucial role in recycling nutrients back into the ecosystem, making them available for producers and other organisms.
5. Conclude that decomposers are the prokaryotic organisms responsible for breaking down dead organic matter, as they are specifically adapted to this role in the environment.
