Which of the following statements correctly describes the difference between food webs and food chains in the context of organic chemistry?
A
Food webs represent multiple interconnected food chains, showing a more complex network of energy flow.
B
Food chains include all possible interactions between organisms, whereas food webs focus on a single species.
C
Food chains depict a single linear pathway of energy flow, while food webs show only one organism at each trophic level.
D
Food webs are simpler and less detailed than food chains, focusing only on primary producers and consumers.
Verified step by step guidance1
Understand the context: In organic chemistry, food webs and food chains are not directly related to chemical reactions but are ecological concepts that describe energy flow in ecosystems.
Define a food chain: A food chain is a linear sequence of organisms where nutrients and energy pass as one organism eats another. It typically starts with a primary producer and ends with a top predator.
Define a food web: A food web is a more complex network of interconnected food chains. It represents multiple pathways through which energy and nutrients flow within an ecosystem, showing how different food chains are linked.
Compare food chains and food webs: Food chains are simpler and depict a single pathway of energy flow, while food webs illustrate a more complex and interconnected network of multiple food chains.
Identify the correct statement: Based on the definitions, the statement that correctly describes the difference is that food webs represent multiple interconnected food chains, showing a more complex network of energy flow.
