Question

the importance of food webs
what extra information is provided by food webs?

based on the food chain the bear only eats deer and therefore, should be a carnivore. however, this food web might tell us another story.

does the evidence provided in the food web, support the conclusion that grizzly bears are carnivores?

○ yes, even in the food web the bear still consumers deer, therefore it is a carnivore.
○ no, although the bear still consumes deer in the food web, it also eats berries from plants, therefore it is an omnivore.
○ no, the bear only consumes berries in the food web, therefore it is a herbivore.
○ there is not enough evidence in the food web to classify the bear’s eating behavior.

Explanation:

To determine the correct answer, we analyze the food web and the options:

• Option 1: Incorrect. Just eating deer (animal) doesn't make it a carnivore if it also eats plants (berries).
• Option 2: Correct. The bear eats deer (animal) and berries (plant), so it's an omnivore (eats both plants and animals), so the conclusion that it's a carnivore is not supported.
• Option 3: Incorrect. The bear does eat deer (animal) as per the food chain and web context, so it's not only a herbivore.
• Option 4: Incorrect. The food web shows it eats deer (animal) and berries (plant), so there is enough evidence to classify it as omnivore, so the "not enough evidence" claim is wrong.

Answer:

B. No, although the bear still consumes deer in the food web, it also eats berries from plants, therefore it is an omnivore.
