What are the differences between a food web and food chain?

• Food chain is linear, while food web is interconnected.
• Food chain represents predator-prey relationships, while food web represents symbiotic relationships.
• Food chain involves only one species, while food web involves multiple species.
• Food chain is circular, while food web is linear.

Compare and Contrast Food Webs and Food Chains

• Food chains are interconnected and show multiple paths of energy flow, while food webs are linear and show a single path of energy flow.
• Food chains are static and unchanging, while food webs are dynamic and constantly evolving.
• Food chains are more complex than food webs due to their interconnected nature.
• Food chains are linear and show a single path of energy flow, while food webs are interconnected and show multiple paths of energy flow.
