Briefly explain an ecosystem food web and one common misconception about it.

# Ecosystem Food Web A **food web** is a network of interconnected food chains showing how energy and nutrients flow through an ecosystem. Unlike a simple linear food chain, it illustrates the complex reality that most organisms eat multiple food sources and are eaten by multiple predators, creating a web-like pattern of feeding relationships. ## Common Misconception **"Removing one species won't matter much because others can just eat something else."** In reality, food webs are often more fragile than they appear. Species play specific roles, and removing one can trigger **cascading effects** throughout the entire system. For example, eliminating a top predator can cause herbivore populations to explode, leading to overgrazing and plant loss, which then affects countless other species. The interconnections mean that disturbances rarely stay isolated—they ripple through the web in unexpected ways.
