They’re pretty flexible about what they eat, chowing down on whatever prey is plentiful and switching to other foods if a prey population is low. In this way, apex predator sharks keep the food web in balance. Areas with healthy shark populations tend to have lots of other species, too—aka more biodiversity.
Which shark is at the top of the food chain?

How does an ecosystem get its food?
In most ecosystems, organisms can get food and energy from more than one source, and may have more than one predator. Healthy, well-balanced ecosystems are made up of multiple, interacting food chains, called food webs. Ask volunteers to come to the front of the room and draw a pyramid and a web.
