Solution
The correct option is C Arctic cod fish population will decrease ∙ Food chain is a series of organisms with a relationship of who eats what. ∙ Therefore, when the population of sea algae drops down, every organism in the chain that depends on it for food will eventually face the scarcity of food. ∙ Thus, the population of the consumers i.e. zooplankton, arctic cod fish, seal and polar bear will decrease.
