Question

this food web is from an ocean ecosystem in the ross sea, off the coast of antarctica. which arrows show matter moving from a producer to a primary consumer? select all that apply. the arrow between the microzooplankton and the salps the arrow between the ice algae and the salps the arrow between the diatom and the krill

Explanation:

Producers are organisms that can make their own food through photosynthesis (like diatoms, ice - algae). Primary consumers eat producers. We check each option to see if it shows a producer being consumed by a primary consumer. The arrow from microzooplankton to salps is incorrect as microzooplankton are not producers. The arrow from ice - algae to salps and from diatom to krill show matter moving from producers (ice - algae and diatom) to primary consumers (salps and krill).

Answer:

• the arrow between the ice algae and the salps
• the arrow between the diatom and the krill
