Grade 5 Unit 5 Lesson 1 and 2 An Ocean of Food Chains and Food Webs
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.

white shark ( Carcharodon carcharias) Most white sharks (Carcharodon carcharias) weigh between 680 and 1,800 kg (1,500 and 4,000 pounds), but some weighing more than 2,270 kg (about 5,000 pounds) have been documented.

Tiger Shark Food Web
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.

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.

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.

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.

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.

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.

Sharks are a diverse group of mobile predators that forage across varied spatial scales and have the potential to influence food web dynamics. The ecological consequences of recent declines in.

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.

A food web consists of all the food chains in a single ecosystem.Each living thing in an ecosystem is part of multiple food chains.Each food chain is one possible path that energy and nutrients may take as they move through the ecosystem.All of the interconnected and overlapping food chains in an ecosystem make up a food web. Trophic Levels Organisms in food webs are grouped into categories.

Here's how it works: when the tide rises, sharks make hunting raids into the shallow lagoons. The fish stop eating and hide instead. But during low tide, the predators are isolated in deeper.

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.
