this food web is from an ocean ecosystem in the ross sea, off the coast of antarctica. which arrows show matter moving from a secondary consumer to a tertiary consumer? select all that apply. the arrow between the silverfish and the adélie penguin the arrow between the krill and the crabeater seal the arrow between the salps and the emperor penguin

Answer

Explanation:

Step1: Identify secondary and tertiary consumers

In a food - web, secondary consumers eat primary consumers, and tertiary consumers eat secondary consumers. Analyze each organism in the food - web. Krill, salps, and silverfish are secondary consumers as they eat primary consumers like phytoplankton or other small organisms. Crab - eater seals, Adélie penguins, and emperor penguins are tertiary consumers as they eat secondary consumers.

Step2: Check each arrow

  • The arrow between silverfish (secondary consumer) and Adélie penguin (tertiary consumer) shows matter moving from a secondary consumer to a tertiary consumer.
  • The arrow between krill (secondary consumer) and crab - eater seal (tertiary consumer) shows matter moving from a secondary consumer to a tertiary consumer.
  • The arrow between salps (secondary consumer) and emperor penguin (tertiary consumer) shows matter moving from a secondary consumer to a tertiary consumer.

Answer:

the arrow between the silverfish and the Adélie penguin, the arrow between the krill and the crabeater seal, the arrow between the salps and the emperor penguin
