Which of the following best describes a food web? a A diagram showing only producers and consumers b A complex network of interconnected food chains C A single linear pathway of energy flow d A list of all species in an ecosystem e A representation of energy flow in one direction

### Step 1<br />A food web is a graphical representation of the feeding relationships among species in an ecosystem. It is a complex network of interconnected food chains, which are simpler sequences of who eats whom.<br /><br />## Step 2<br />Option a is incorrect because a food web includes not only producers and consumers but also decomposers and detritivores.<br /><br />## Step 3<br />Option c is incorrect because a food web is not a single linear pathway of energy flow. It is a complex network of multiple pathways.<br /><br />## Step 4<br />Option d is incorrect because a food web is not of all species in an ecosystem. It only includes those species that are part of the feeding relationships.<br /><br />## Step 5<br />Option e is incorrect because a food web represents the flow of energy in multiple directions, not just one.<br /><br /># Answer: <br />'b' is the correct answer. A food web is best described as a complex network of interconnected food chains.
