Three food chains (a-c) can be created from the food web represented in Figure 16-9. Food webs are important because they show the direct relationships between organisms; however, they also illustrate the indirect relationships that organisms have with each other. Let's look at an example from the Figure 16-9 food web. Sharks prey on parrotfish.

Marine food webs. Resource. Add to collection. Feeding relationships are often shown as simple food chains - in reality, these relationships are much more complex, and the term 'food web' more accurately shows the links between producers, consumers and decomposers. A food web diagram illustrates 'what eats what' in a particular habitat.
Sharks, The Apex Predators — Save The Sharks
In this way, the sun's energy is transferred up aquatic food webs, eventually feeding apex predators such as sharks and other large fish. What factors shape food webs? Aquatic food webs can be characterized by the number of trophic levels and the amount of biomass in each level. Nutrient availability is central in shaping food webs.
Food Web Gammerhead Seagle
Aquatic food webs. Food webs describe who eats whom in an ecological community. Made of interconnected food chains, food webs help us understand how changes to ecosystems — say, removing a top predator or adding nutrients — affect many different species, both directly and indirectly. Phytoplankton and algae form the bases of aquatic food webs.

These groups include higher level predators such as sharks. In reality most ecosystems are more complicated than a simple chain of feeding interactions. Many species consume more than one type of species, creating a complex web of interactions known as a food web.

And that's bad news for the creatures even lower on the food web. Along the East Coast of the United States, only sharks that are at least 2 meters (6.6 feet) long are tough enough to eat a lot of the medium-size sharks, rays, and skates living in those waters. Eleven large shark species in the region fit into that category.

As apex predators, tiger sharks and other shark species play a critical role in maintaining the health of ocean ecosystems. But shark populations are decreasing around the world, due to overfishing and the high demand for shark fin soup. When their numbers plummet, it can have a chain reaction on ocean food webs, impacting seabirds and commercially important fish species, such as tuna and jacks.

Shark populations are dwindling worldwide, and scientists are concerned that the decline could trigger a cascade of impacts that hurt coral reefs. But a new paper published in Ecology suggests that the effects of shark losses are unlikely to reverberate throughout the marine food web. Instead, the findings point to physical and ecological.
Marine Food Pyramid National Geographic Society
Sharks are carnivores, so they get energy by eating other animals. Predators like sharks help keep prey populations balanced. If a prey population gets too big, they might deplete their own food source. Food webs can show us how everything is connected. Materials. 1 clothes hanger (or a straight rod, like a chopstick or a skewer) Crayons, or.
Food chain Definition, Types, & Facts Britannica
Sharks keep the food web in balance. Many large shark species are apex predators at the top of the ocean's food web. 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.

Marine Food Pyramid. This food pyramid displays a basic marine food web. Organisms on the first trophic level, such as plants and algae, are consumed by organisms on the second trophic level, such as conchs and blue tangs. At the top of the food web is an apex predator, a shark. A pyramid displays different trophic levels in a marine food web.

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.
