Who eats who in an ecosystem?
A food chain outlines who eats whom. A food web is all of the food chains in an ecosystem. Each organism in an ecosystem occupies a specific trophic level or position in the food chain or web.
What are 2 predators in the ocean?
Top of the Food Chain: 5 Deadly Marine Predators
- Killer Whales. When you think of top ocean predators, you probably think of sharks.
- Great White Shark. They can smell a single drop of blood floating in 10 billion drops of water.
- Polar Bears.
- Leopard Seals.
- Sea Lions.
Who is at the top of the food chain in the ocean?
killer whale
The orca, or killer whale is at the top of the marine food chain. In spite of the fact that they are called “killer whales,” orcas are actually dolphins. Orcas have 4-inch long teeth that they use to feast on other ocean animals, which can include seals, sea lions, sharks, seabirds, fish, and even whales.
What are primary consumers in the ocean?
Primary consumers in the ocean include zooplankton, small fish, and crustaceans. The secondary consumers are fish, coral, penguins, whales, and other species that eat the zooplankton. The top predators in the ocean, sharks, killer whales, and leopard seals, eat both primary and secondary consumers.
Who eats a bird?
Hungry birds Of course birds are animals too, so many of them may also end up as someone else’s dinner. Weasels, snakes and foxes all eat birds – and so do other birds, including hawks, owls and gulls.
What eats a shark?
Though the great white is considered the top marine predator, orcas may actually rule the oceans, new observations suggest.
Who is the queen of the ocean?

Is a jellyfish a secondary consumer?
Fish, jellyfish and crustaceans are common secondary consumers, although basking sharks and some whales also feed on the zooplankton.
Is Arctic cod a consumer?
Ocean Food Chain The primary consumers in the Arctic Ocean are phytoplankton and crustaceans that consume the zooplankton. Harp seals are secondary consumers, which mainly eat fish like Arctic cod and Arctic char, and some crustaceans. The top predators, or tertiary consumers, are polar bears and the Orca whale.
Who are the Predators in the marine food chain?
The large predators that sit atop the marine food chain are a diverse group that includes finned (sharks, tuna, dolphins), feathered (pelicans, penguins), and flippered (seals, walruses) animals. These apex predators tend to be large, fast, and very good at catching prey. They are also long-lived and usually reproduce slowly.
Which is the only animal that eats fish?
Mammals that eat fish include dolphins, black and brown bears, seals and sea lions, sperm whales, gray whales, killer whales, fin whales, and humpback whales. Other mammals that eat fish are walruses, raccoons, skunks, otters and several species of wild cats, including ocelots, fishing cats and servals.
How is the food chain linked to the ocean?
A food web is a system of interconnected food chains. A food chain is a top-to-bottom set of animals and plants. They are linked to each other because those on top eat those below. The bottom level of the ocean’s food chain is made up of one-celled organisms called phytoplankton.
How are marine species linked to the food web?
Together, these different species make up about 15 percent of the planet’s plants and animals. Most marine species are tied together through the food web. A food web is a system of interconnected food chains. A food chain is a top-to-bottom set of animals and plants. They are linked to each other because those on top eat those below.
