If fungi were affected by acid rain, resulting in low yields, there would be fewer decomposers in the food web, and thus no nutrient recycling in the food web.
A food web is a graphical representation of what-eats-what in an ecological community that is formed by the natural interconnection of food chains. The food web is also known as a consumer-resource system. Every living thing in an ecosystem is a part of several food chains. Each food chain represents one possible path for energy and nutrients as they move through the ecosystem.
The food web is a useful conceptual tool for depicting the feeding relationships among species within a community, revealing species interactions and community structure, and comprehending the dynamics of energy transfer in an ecosystem. Food webs, unlike food chains, are never straight. A food web provides alternative food availability pathways. A food web with more alternatives makes the ecosystem more stable.
