Marine Food Chain
Seaweed is eaten by a variety of animals that live in and around the ocean. Most of the animals that eat seaweed are smaller marine lifeforms, such as. Crustaceans are known to eat seaweed. Therefore, there is more than one animal that eats it which includes crayfish, crabs, lobsters and plankton. What eats bacterica in the ocean? almost every.
It lets scientists map out who eats who, from the smallest microorganisms to the largest predators. The lowest trophic level In the twilight zone, for example, is made up of plankton that get their energy from sunlight. Animals that eat those plankton make up a second, higher trophic level, and are in turn eaten by animals in an even higher trophic level. These levels continue up the food web to include animas predators like sharks, whales, and humans.
Learning how its food webs works will help us seawesd those fisheries sustainably in the future. It may also help us understand how the twilight zone affects global climate by absorbing and sequestering carbon dioxide. Most of it is tiny, just how to build mini half pipe few inches long or less. But some, like gelatinous siphonophores, can form chains that extend as much as feet, making them among the biggest animals that exist today.
Even the smallest twilight zone inhabitants can be powerful through sheer number, however. A tiny but fierce-looking fish called a bristlemouth is the most abundant vertebrate on the planet, likely numbering more than a quadrillion individuals. Copepods like these pictured are the base of the ocean twilight zone food web.
There are many predators at the top of the ocean twilight zone food webs. Some commercially important species like swordfish and tuna dive from the surface down into the twilight zone to feed, as do animals like aet elephant seals, sperm whales, and even king penguins.
The majority of the predators in the twilight zone spend their entire lives in its dark waters, however. These include bizarre-looking species like bristlemouth, fangfish, viperfish, and angler fish.
Microbes, plankton, jellies, and fish—everything living in the twilight zone has amazing adaptations for life in such an extreme environment.
Many animals can produce their own light using a method called bioluminescence. These glowing patches of their bodies can help them camouflage themselves, scare off predators, or even attract prey.
Since little sunlight makes it to the twilight zone, many animals hunt using only specialized organs that detect movement and vibration in the surrounding water. Some researchers are tagging top predators with high-tech sensors which can track their rhe through the ocean, revealing how the depth and frequency of their dives and provide clues to where and when they might go to feed. A third group of scientists is collecting water samples from the twilight zone to study stable isotopes and environmental DNA —traces of DNA left behind by animals—which will tell them exactly what species are present in the nearby ocean, and where their position in the food web may be.
As surface waters become dark after sundown, zooplankton, mollusks, fish, crustaceans, and other marine organisms rise up from the twilight zone to feed on phytoplankton. Since those phytoplankton create energy from sunlight—and absorb carbon dioxide in the process—this migration is both a vital step in the marine food web and a critical part of carbon sequestration in the ocean.
