Question
Sperrm whales Part G Suppose that humans increase their consumption of Antarctic fishes, causing a significant reduction in the size of fish populations. What would be the most likely effect of a reduction in the size of Antarctic fish populations?

The sperm whale population would decrease
Reason: In the given food web, the sperm whale population is dependent on the Antartic fish population. The excessive consumption of these fishes by humans reduces their availability to sperm whale. As a result, the population of sperm whale would decrease.
The carnivorous plankton population would increase
Reason: Antartic fish are dependent on carnivorous plankton for their food. Excessive consumption of Antartic fish by humans reduces their population. This significantly affects the population of carnivorous planktons. Due to the absence of predators, the population of carnivorous plankton would increase.
The elephant seal population would decrease
Reason: Elephant seals are directly dependent on Antartic fish. Although elephant seals consume squids, the population of squids are again dependent on the population of fishes. Due to the excessive consumption of Antartic fishes by humans, the population of Elephant seal declines.
