Explanation:

A food chain is the unidirectional pathway of the flow of energy and matter from one organism to another organism through by eating one another.

The food chain consists of the organism in sequence starting from a producer to primary consumer, secondary consumer and tertiary consumer.

In the marine system, the phytoplanktons are considered producers as they produce their own food through photosynthesis.

The phytoplanktons are eaten by the primary consumers which are shrimp and the shrimp are eaten by the secondary consumer which is salmon in the given case.

Thus, Salmon feed on  shrimp and need  oxygen to live is the correct answer.
