Whales are important to the life cycle of the ocean, especially the nutrient cycling. For example, their feces make organic carbon easily accessible to the tiny organism that feeds on them. This includes the planktons or krill that whales eat as their main source of food. If the whale dies, its carcass carry tons of the organic carbons, falling down to the sea bed and become a reservoir for more sea life to thrive on. These carcasses become the main food source that keeps the deep sea environment that tends to not have a bounty of such nutrients. Also, there are the millions of krill and planktons that the whale feed on daily. What happen if you remove the whales from the food chain? There will be too much krill and planktons in the ocean, which means less food for the rest of the organism. As we know, the balance of food chain is important to ensure the balance of the ecosystem, so there is no overpopulation of one species and crowding out of resources for others. With that said, whales are just as important as any other marine animals in the ocean, playing the important role of feeding and maintaining the numbers of small organisms in the ocean.
