Which organisms are specifically associated with breaking down dead organic material?

The correct answer highlights the role of micro-organisms in ecosystems, particularly in the decomposition process. Micro-organisms, which include bacteria and fungi, are crucial for breaking down dead organic material, such as fallen leaves, dead animals, and other organic debris. They metabolize complex organic compounds and convert them into simpler substances, facilitating the recycling of nutrients within the ecosystem.

This decomposition process not only helps in nutrient cycling but also supports soil health by improving soil structure and fertility, thereby ensuring that other organisms, such as plants (producers), have access to essential nutrients. In contrast, carnivores primarily consume living organisms, while producers utilize sunlight to create energy through photosynthesis, and plants serve as primary producers in a food web.
