Energy Flow in Ecosystems

Question 2 • AISD-Biology B CR (25-26)

Which statement best contrasts food chains and food webs?

Answer
A
Food webs show a single path of energy in an ecosystem, and food chains show all the overlapping food chains in that ecosystem.
B
Food chains show a single path of energy in an ecosystem, and food webs show all the overlapping food chains in that ecosystem.
C
Food webs show the path of energy in an ecosystem, and food chains show the path of nutrients in that ecosystem.
D
Food chains show the path of energy in an ecosystem, and food webs show the path of nutrients in that ecosystem.

Explanation

A food chain shows one route by which energy passes from one organism to another. A food web combines many connected food chains, showing the overlapping feeding relationships in an ecosystem. Therefore, the best contrast is that food chains show a single path of energy, while food webs show overlapping food chains.
