below is a food web from shenandoah national park, a forest ecosystem in virginia. which two of the following arrows show matter moving from a secondary consumer to a tertiary consumer? the arrow between the pine vole and the gray fox the arrow between the swallowtail caterpillar and the gray fox the arrow between the pine vole and the black racer the arrow between the beaver and the bobcat the arrow between the persimmon tree and the black bear
Answer
Explanation:
Step1: Identify secondary and tertiary consumers
Secondary consumers eat primary - consumers. Tertiary consumers eat secondary - consumers. In this food - web, pine vole and beaver are primary consumers (eat plants). Swallowtail caterpillar is also a primary consumer. Gray fox, black racer are secondary consumers. Bobcat is a tertiary consumer.
Step2: Analyze each option
- The arrow between the pine vole (primary consumer) and the gray fox (secondary consumer) is from primary to secondary, not what we want.
- The arrow between the swallowtail caterpillar (primary consumer) and the gray fox (secondary consumer) is from primary to secondary, not what we want.
- The arrow between the pine vole (primary consumer) and the black racer (secondary consumer) is from primary to secondary, not what we want.
- The arrow between the beaver (primary consumer) and the bobcat (tertiary consumer) is not from secondary to tertiary.
- The arrow between the persimmon tree (producer) and the black bear is from producer to primary/omnivore, not what we want. However, if we assume correct understanding of consumer levels, we need to find arrows from secondary to tertiary. In a proper analysis, gray fox is a secondary consumer and bobcat is a tertiary consumer. Also, black racer is a secondary consumer and bobcat is a tertiary consumer. But among the given options, if we consider the food - web logic, the arrow between the beaver (primary consumer) is wrong in the context of the question. The correct ones should be based on the relationship where secondary consumers like gray fox are eaten by bobcat (tertiary consumer). But since the options are not ideal, we assume the intention might be to consider the arrow between the gray fox and the bobcat and the arrow between the black racer and the bobcat (not given in options). If we have to choose from the given options, we note that the arrow between the beaver (primary consumer) and the bobcat is incorrect for the question's requirement. But if we assume some mis - labeling and consider the general concept, the arrow between the gray fox (secondary consumer) and the bobcat (tertiary consumer) and the arrow between the black racer (secondary consumer) and the bobcat (tertiary consumer) would be correct. Since we don't have all correct options, we can't give a definite correct answer from the given ones based on strict consumer - level definitions. But if we assume some leniency, we would look for arrows from secondary to tertiary.
