Final answer:
The removal of krill from the oceanic food web would have a significant impact on the ecosystem, leading to a disruption of the food chain and a decrease in populations of marine animals that depend on krill as a food source.
Step-by-step explanation:
If all of the krill were removed from the oceanic food web, it would have a significant impact on the ecosystem. Krill are a primary food source for many marine animals, including whales, penguins, and seals. Without krill, these animals would struggle to find enough food, leading to a decrease in their populations. This would disrupt the balance of the food web, as the absence of krill would affect all levels of the food chain.
