Which two of the following arrows show matter moving from a secondary consumer to a tertiary consumer?
Understand the Problem
The question asks to identify which two arrows in the given food web diagram represent the transfer of matter from a secondary consumer to a tertiary consumer. This requires understanding the roles each organism plays in the ecosystem (producer, primary consumer, secondary consumer, tertiary consumer) and tracing the flow of energy/matter between them.
Answer
The arrows between the short-tailed weasel and the snowy owl, and the brown lemming and the Arctic fox, show matter moving from a secondary consumer to a tertiary consumer.
Based on the food web, the arrows that depict matter transfer from a secondary consumer to a tertiary consumer are:
- the arrow between the short-tailed weasel and the snowy owl
- the arrow between the brown lemming and the Arctic fox

More Information
In a food web, energy and nutrients flow from one organism to another. Consumers are categorized by what they eat: primary consumers eat producers (plants), secondary consumers eat primary consumers, and tertiary consumers eat secondary consumers. This transfer of matter is represented by arrows in the food web diagram.
Tips
When determining the flow of matter in a food web, carefully consider the diet of each organism and its position in the web. Producers are always at the base, followed by primary, secondary, and tertiary consumers.
