Which of the following best describes the difference between a food chain and a food web?
A
A food chain includes only herbivores, while a food web includes both herbivores and carnivores.
B
A food chain represents energy flow in an ecosystem, while a food web represents the physical connections between organisms.
C
A food chain is found only in terrestrial ecosystems, while a food web is found only in aquatic ecosystems.
D
A food chain is a linear sequence of organisms where each is eaten by the next, while a food web is a complex network of interconnected food chains.
Verified step by step guidance1
Step 1: Understand the definitions of a food chain and a food web. A food chain is a linear sequence of organisms where each organism is eaten by the next one in the chain. A food web, on the other hand, is a complex network of interconnected food chains within an ecosystem.
Step 2: Analyze the options provided in the problem. The first option suggests a difference based on the types of organisms included, which is incorrect. The second option confuses the representation of energy flow and physical connections, which is not accurate. The third option incorrectly categorizes ecosystems.
Step 3: Focus on the correct answer provided. It states that a food chain is a linear sequence, while a food web is a complex network. This highlights the structural difference between the two concepts.
Step 4: Consider the implications of these definitions. A food chain simplifies the flow of energy by showing a direct path, whereas a food web illustrates the multiple pathways through which energy can flow in an ecosystem.
Step 5: Reflect on the importance of understanding these concepts in ecology. Recognizing the difference between food chains and food webs helps in understanding the complexity and interdependence of organisms within an ecosystem.
