Food Web vs Food Chain

Comparing Food Chains and Food Webs

• A food chain is a linear sequence of organisms showing who eats whom, whereas a food web is a complex network of food chains that are interconnected.
• A food web is a more realistic representation of the feeding relationships in an ecosystem because it shows the multiple predator-prey relationships between different species.

Defining a Food Web

• A food web is a network of food chains that are interconnected and show the feeding relationships between different species in an ecosystem.

Ecological Realism of Food Webs

• Food webs are more ecologically realistic than food chains because they take into account the complexity of feeding relationships in an ecosystem.
• In a food web, a single species can be a part of multiple food chains, which is a more accurate representation of the natural world.
• Food webs also recognize that a single species can have multiple predators and prey, unlike food chains which imply a linear sequence of predation.
