However, because blue whales feed low on the food chain, there is a lesser chance for bioaccumulation of organic chemical contaminants. [160] Analysis of the earwax of a male blue whale killed by a collision with a ship off the coast of California showed contaminants like pesticides, flame retardants, and mercury.

A food web model is a network of food chains. Each food chain starts with a primary producer or autotroph, an organism, such as an alga or a plant, which is able to manufacture its own food. Next in the chain is an organism that feeds on the primary producer, and the chain continues in this way as a string of successive predators.

The largest animals ever known to have lived on Earth ingest up to 96 pounds of microplastics a day, the study suggested.
"Alfaguara" was the name given to blue whales by Chilean whalers. The focus of the project is on preservation of these endangered animals, the largest in the world. [ 1 ] The project is operated by the Centro de Conservacion Cetacea (CCC), established in 2001. [ 2 ]
The release of iron from whale feces encourages the growth of phytoplankton in the sea, [5] which not only benefits the marine food chain, but also sequesters carbon for long periods of time. [5] When phytoplankton, which is not consumed in its lifetime, perishes, it descends through the euphotic zone and settles down into the depths of sea.
Arctic food webs are considered simple, meaning there are few steps in the food chain from small organisms to larger predators. For example, pteropods are "a key prey item of a number of higher predators – larger plankton, fish, seabirds, whales". [117]
