Food Chain In The Deep Ocean

Deep seafloor nutrient vital in global food chain Date.

Food chain in the deep ocean. Their ultimate fate is a rain of organic debris out of the surface-mixed layer of the ocean. These apex predators tend to be large fast and very good at catching prey. On a global scale the mechanisms and overall rate of this process are poorly known.

The next level of the marine food chain is made up of animals that feast on the seas abundant plant life. Overall the new results suggest that in oxygen-bearing deep-sea sediments Thaumarchaea convert inorganic carbon into biomass and therefore serve as the basal level of the food chain. 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.

Cold seeps are areas where methane and hydrogen sulfide are released into the ocean. In these environments food chains do not begin with plants or algae that make food from sunlight. Sea-floor cold seeps are just such places.

A simplistic food chain of the ocean biomes will consist of phytoplanktons zooplanktons primary consumers and tertiary consumers. Phytoplankton and algae form the bases of aquatic food webs. A food chain is a top-to-bottom set of animals and plants.

University of Leeds Summary. Snipe eels play an important role in transferring energy from the highly productive surface waters to the deep ocean. A food chain in the ocean begins with tiny one-celled organisms called diatoms which make their own food from sunlight.

In the deep ocean there is no sunlight and therefore no photosynthesis yet life flourishes in certain places. Decomposers are bacteria that chemically break down organic matter. They are also long-lived and usually reproduce slowly.
