Which concept represents the interactions between producers, consumers, and decomposers?

The concept that best represents the interactions between producers, consumers, and decomposers is the food web. A food web is a complex network of interconnected food chains that illustrates how energy and nutrients flow through an ecosystem. It captures the many feeding relationships among organisms, showing how various species interact as they consume and are consumed within their environment.

Producers, such as plants, form the base of the food web by converting solar energy into chemical energy through photosynthesis. Consumers, including herbivores and predators, feed on these producers and one another, while decomposers, like fungi and bacteria, break down dead organic matter, returning vital nutrients to the soil and completing the cycle of energy flow.

The food web model provides a more accurate representation of ecosystem dynamics compared to a single food chain, as it accounts for the multiple pathways through which energy and nutrients are transferred between different organisms. This interconnectedness is crucial for maintaining ecological balance and sustainability.
