A normal whales diet will consists of three main things. Fish, squid and tiny little plankton. They swim through the water, mouth open to catch the plankton.

Belugas are toothed whales, they don't deliberately eat things as small as krill.
Pollution can impact whales in two ways:As top predators (they eat things that eat things,that eat things) they are at the receiving end (get aconcentrated dose of) of the bioaccumulation of contaminants like PCBs and mercury.Low levels of pollution and climate change can remove the species of food that whales eat. They then starve.
There are not really "three things" that cows eat, it's more or less the three types of things cows eat. Cows can only eat one thing: plant matter. The three main types of plant matter they eat are fresh green grass, roughage in the form of hay or silage, and grain.

The three main types of killer whales are transient, which eat mammals; residents, who live in larger groups and feed on birds, fish, and invertebrates such as squid; and offshore,which eat fish and may also eat mammals. Not much is known about offshore killer whales.
Whales will only eat octopus if they are starving and the octopus is a baby otherwise they will eat fish also depending on the type of whale. A sperm whale's main food is giant squid.
Whales, that are filter feeders, use baleen plates to sieve their main food of krill.
