Where is a shark on the food chain?
apex predator
Sharks are an apex predator, which means they are at the top of the food chain.
What is a shark explanation?
Sharks are a group of elasmobranch fish characterized by a cartilaginous skeleton, five to seven gill slits on the sides of the head, and pectoral fins that are not fused to the head. Modern sharks are classified within the clade Selachimorpha (or Selachii) and are the sister group to the rays.
How do sharks balance the food chain?
Sharks keep ocean ecosystems in balance Sharks limit the abundance of their prey, which then affects the prey of those animals, and so on throughout the food web. Because sharks directly or indirectly affect all levels of the food web, they help to maintain structure in healthy ocean ecosystems.
What level are sharks in the food chain?
apex predators
Sharks are often considered apex predators in their ecosystem mainly because they have few natural predators. As apex predators, sharks feed on animals below them in the food chain, regulating and maintaining the balance of marine ecosystems.
Why are sharks in the marine food chain in danger?
Unfortunately because of human activities like overfishing, industrial pollution, and habitat destruction, the marine food chain is threatened. So it is really important to understand what sharks eat in order to understand how we can protect their food sources so sharks do not face extinction.
What kind of shark eats crustaceans in the ocean?
Crustaceans are hunted by a variety of sharks but most commonly they are eaten by bottom-dwelling sharks like Catsharks, Horn Sharks, Angel Sharks, Leopard Sharks, and Wobbegongs. Most sharks that eat crustaceans have biological adaptations like flatter teeth and strong jaws to crunch through the shells of these animals.
How does the food chain explain which organism eats another organism?
A food chain explains which organism eats another organism in the environment. The food chain is a linear sequence of organisms where nutrients and energy is transferred from one organism to the other. This occurs when one organism consumes another organism. It begins with producer organism, follows the chain and ends with decomposer organism.
What kind of food does a filter feeder shark eat?
Examples of zooplankton include fish eggs and juvenile fish, jellyfish, segmented worms, tiny crustaceans like shrimp, and larvae. Zooplankton is the primary source of food for filter-feeder sharks.
How are sharks important for the food chain?
As apex predators, sharks play an important role in the ecosystem by maintaining the species below them in the food chain and serving as an indicator for ocean health. They help remove the weak and the sick as well as keeping the balance with competitors helping to ensure species diversity.
What is the food of sharks?

What is shark ecology?
Covering over 70% of the earth’s surface the ocean contains a series of dynamic and incredibly varied ecosystems. Species occupying the highest trophic level in a food web are known as apex predators and include many species of shark. …
