Answer 1

A

Step-by-step explanation:

A.) Zooplankton to fish to krill to the blue whale.

Answer 2

Option-B

Step-by-step explanation:

A food chain represents the linear pathway of the flow of matter and energy in the ecosystem through consumption of organism as food.

The food chain varies from ecosystem to ecosystem as the organism are different in the different ecosystem but the trophic level remains the same that is the basal trophic level must be producers.

In the given question, the aquatic ecosystem food chain begins with the producers like seaweed which forms the basal trophic level. The seaweeds can be consumed by the crab (primary consumers) and the crab can be eaten by the squid (secondary consumer). The squid can be eaten by the seal and the seal can be eaten by the whale.

Thus, Option-B is the correct answer.
