What would happen to the food chain if whales went extinct?
Whales play an important role in stabilizing the aquatic food chain and reproduction of other species. As more whales are killed, the ocean’s food distribution becomes destabilized and causes changes in the food supply of many other kinds of marine life.
Where is whale in 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.
What happens when whales are extinct?
The descent. Decay sets in soon after the death of a whale, as the insides begin to decompose. The animal then expands with gas and sometimes floats up to the ocean’s surface, where it can be scavenged by sharks and seabirds.
Why are whales important to the food chain?
Whales are at the top of the food chain and have an important role in the overall health of the marine environment. Whales play a significant role in capturing carbon from the atmosphere; each great whale sequesters an estimated 33 tons of CO2 on average, thus playing their part in the fight against climate change.
Can the world survive without whales?
Whales play an amazing role in an ecosystem that keeps every creature on Earth alive, including you! Whales play a vital role in the marine ecosystem where they help provide at least half of the oxygen you breathe, combat climate change, and sustain fish stocks.
Are whales at the top of the food chain?
Killer whales are apex predators, which means they have no natural predators. They hunt in packs, much like wolves, which are also at the top of their food chain.
Are blue whales at the top of the food chain?
Whales are at the top of the food chain and have an important role in the overall health of the marine environment. During the 20th century, the blue whale was an important whaling target and even after it was protected and commercial whaling stopped in 1966, exploitation efforts by the former Soviet Union persisted.
What animal eats a whale?
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.
What is the killer whales natural predator?
Why did whales almost go extinct?
Whaling history and process Whaling is a method of hunting whales for their meat, oil and blubber. The hunting of whales on an industrial scale began in the 17th century and into the 20th century, and as a result of the quantities caught the whale is an endangered species.
Why are whales extinct?
Several factors contribute to whales’ current endangered status, such as overfishing, pollution, dam/bridge construction, private/commercial boating, and commercial whaling. Still, commercial whaling has had the largest effect on the endangered status of today’s whale populations.
Do whales have any predators?
Whales basically have two enemies: Orcas (killer whales, which in fact are not whales, but dolphins) and human beings. Only one type of Orca, the transient orca, is known to attack whales and other marine mammals. Transients Orcas are sometimes referred to as “wolves of the sea” as they will hunt in packs.
Who is the apex predator of the ocean?
Killer whales
Great white sharks, to be exact. But the true ruler of the sea is the killer whale. Killer whales are apex predators, which means they have no natural predators. They hunt in packs, much like wolves, which are also at the top of their food chain.
What animal kills whales?
Orcas
Orcas won’t hesitate to attack fish, sea birds, and sea lions. Now, for the first time, a pod of orcas has been documented viciously attacking the largest creature on the planet: an adult blue whale.
Are orcas the top of the food chain?
Killer whales (also called orcas) are apex predators, meaning they are at the top of their food chain. They feed on fish and squid like other odontocetes (toothed whales) do, but will also target seals, sea birds and even whale species far bigger than themselves.

What would it be like if whales went extinct?
Seeing the whales go extinct would be “horrific, embarrassing, every bad word there is,” Webber said. “Every creature has a role to play in the ecosystem,” she said. A healthy ocean ecosystem translates to healthy coastal economies.
Whales are at the top of the food chain and have no predators other than humans. Hunting a top predator of the food chain to endangerment has great consequences and will affect all the creatures below it. This is a food web of the animals in the artic.
How many whales are endangered today?
Though whale protections and public awareness of the inhumaneness of whaling have improved, unfortunately, 7 out of the 13 great whale species are classified as endangered or vulnerable, even after decades of protection. How can we, as individuals, help protect whales from some of the threats they face?
