What Food Chain Sequence, from the Base Up, Would Be

Question

What food chain sequence, from the base up, would be found in the open ocean?
A) zooplankton, phytoplankton, tuna, cod
B) phytoplankton, zooplankton, sand lance, humpback
C) shark, cod, phytoplankton, zooplankton
D) albatross, cod, zooplankton, phytoplankton

Accepted Answer

In the open ocean, the base of the food chain is usually made up of phytoplankton, which are then consumed by zooplankton. Sand lance feed on zooplankton, and humpback whales feed on sand lance, making the food chain sequence: phytoplankton → zooplankton → sand lance → humpback.
