Question

why are food webs considered more realistic than food chains?
a because they do not include decomposers
b because they are easier to draw
c because they show only one pathway
d because they only include producers
e because they show multiple feeding relationships

Explanation:

Food chains represent a single linear sequence of who eats whom. In contrast, food webs depict multiple feeding relationships among organisms. This complexity in food webs more accurately reflects the real - world ecological interactions where most organisms have multiple food sources and are preyed upon by multiple predators.

• Option a: Food webs do include decomposers (not a reason for being more realistic).
• Option b: Ease of drawing is not related to realism.
• Option c: Food webs show multiple pathways (opposite of this option).
• Option d: Food webs include various trophic levels (not just producers).
• Option e: Correct as multiple feeding relationships are a key aspect of the realism of food webs.

Answer:

E. Because they show multiple feeding relationships
