Q:

What is a food chain for a tiger shark?

A:

Tiger sharks exist at the top of the food chain, and they prey on a wide variety of species, including fish, sea turtles and other sharks. Additionally, tiger sharks prey on sea-dwelling birds, catching them as they land on the water’s surface. Mollusks such as sea snails, conchs and whelks also serve as prey for the opportunistic sharks. Tiger sharks are also scavengers that have been known to eat garbage.

According to the Shark Bay Ecosystem Research Project, tiger sharks are important in regulating the population of many of the small species that share their habitat. This includes those species that the tiger sharks hunt, as well as those that they rarely eat. This occurs because the non-prey species must still avoid the prowling tiger sharks; because of this, they cannot forage for food as often. This makes it harder for these species to grow, develop and breed successfully.

Although tiger sharks rarely attack humans, they are second to only great white sharks in terms of reported human attacks. In Hawaii, where tiger sharks are common, there is an average of one human attack each year, according to the Shark Bay Ecosystem Research Project.

While tiger sharks are apex predators, they are often caught and eaten by humans.

    What is the food chain for the tiger shark?

    A:

    Tiger sharks probably have a wider diversity of prey than any other shark species. Their primary prey species include fish, sea turtles, mollusks, sea birds and other sharks, but virtually anything swimming in the ocean is fair game. Adult tiger sharks have few predators other than humans, but young tiger sharks must avoid large predatory fish and sharks.

    What is the golden eagle's food chain?

    A:

    According to Nature.com, the golden eagle is at the top of the food chain, above plants, squirrels and scorpions. Plants are considered primary producers and make up the first level of the food chain. Ground squirrels, which are primary consumers, are in the second level and feed on plants. Golden eagles are tertiary consumers, meaning that they prey upon primary and secondary consumers.

    What is the food chain of the American alligator?

    A:

    The American alligator, known to scientists as Alligator mississippiensis, is at the top of the food chain. Called an apex predator, American alligator adults feed on virtually every other creature that shares their habitat, but they fear nothing except for humans and larger alligators. However, its young are not so safe, and many baby alligators are consumed by a variety of aquatic predators.
