Who eats the whale?

Aside from sharks, the only other creature that ever eats a whale is the orca, or killer whale, which is the largest member of the dolphin family and not really a whale at all. Packs of orcas sometimes chase large whales until they are exhausted, and then begin to eat them.

What would happen if killer whales were to vanish?

What would happen if the Orca Whale becomes extinct? If it goes extinct then the population of prey will multiply. Since their main food source is Salmon. There would be more salmon, younger salmon would feed on lots of zoo plankton and small invertebrates, bigger salmon would feed on lots of small fish and krill.

Who eats phytoplankton?

Phytoplankton and algae form the bases of aquatic food webs. They are eaten by primary consumers like zooplankton, small fish, and crustaceans. Primary consumers are in turn eaten by fish, small sharks, corals, and baleen whales.

What would happen if there were no whales?

Were it not for whaling, the animals might have removed 2 million tons of carbon from Earth's atmosphere. In other words, sperm whales fight climate change without trying. So if the whale population dwindled to zero, that would result in boatloads more carbon remaining in the atmosphere.

What eats a blue whale?

Because of their size, power and speed, adult blue whales have virtually no natural ocean predators. The only sea creature known to attack blue whales is the orca whale (scientific name: Orcinus orca) also known as the “killer whale”. They have been known to work in groups to attack blue whales.

Why are whales important to the food chain?

Like all living beings, whales occupy a role in the food chain and thus contribute to the balance of the marine ecosystem. As predators, they feed on fish and invertebrates; as prey, they may be hunted by other predators (sharks, whales, etc.) and by Man. Whales are sentinels of the health of marine environments.

They are eaten by the tertiary consumers, which, I will tell you about in minute.

Why do killer whales not eat humans?

There are a few theories about why orcas don't attack humans in the wild, but they generally come down to the idea that orcas are fussy eaters and only tend to sample what their mothers teach them is safe. Since humans would never have qualified as a reliable food source, our species was never sampled.

Do whales drink water?

Despite a few exceptions, pinnipeds and cetaceans do not usually drink. In most cases, water is supplied by the metabolism of prey proteins (metabolic water) and the oxidation of fat (drinking water). In cetaceans, these waters may be sufficient to maintain a water balance in the body.

Why is whale poop important?

When whales poop, they drop a load of crucial nutrients into the 'topsoil' of the ocean. Their poop fertilizes the surface of the ocean with nutrients that are fundamental to the health of ocean ecosystems, the global nutrient cycle, and the carbon cycle.

Whales play a key part in helping to combat climate change through their role in the marine ecosystem. They play a vital role in the health of the oceans where they help provide up to 50% of our oxygen, combat climate change and sustain fish stocks.

Why do whales jump out of the ocean?

Scientists suspect humpback whales are breaching and slapping their fins and flukes on the surface as a way of communicating. It is believed that all slapping creates sounds used to send messages to other whales, and the big splashes are for sending messages long-distances.
