47K Explore the ocean food web, the complex network of organisms, and how they eat each other to survive. Discover examples of producers and consumers in ocean ecosystems and learn the difference between a food web and food chain. Related...
Sites with high sediment coprostanol concentrations (>0.5 mu g g(-1)) were associated with a lower abundance of basal resources and niche shrinking of the benthic food web, suggesting that eutrophication leads to a funtional loss in the sediment-water interface in this estuary. Our study ...
Why does ocean salinity matter? Why is marine geophysical important to oceanography? Why are krill so important in the marine food web? How does ocean acidification affect sensory function in marine organisms? Why are copepods important to the ocean food web?
Ocean Ecosystems: Hard Bottoms The term "hard bottom" refers to the ocean region close to shore, where wave action prevents the accumulation of muddy sediment that will create a soft bottom. Plants and animals living on or in the seafloor are called benthos. Benthic epifauna reside on or ...
Investigating the long- term relationships of deep-sea biota with their extreme environ- ments within a laboratory simulator is much more cost-effective than that investigating these relationships in the ocean. In the future, more attention should be given to large-scale simulators that can ...

In this work, we initially focus on the MmtN enzyme of Roseovarius indicus B108, a DMSP-producing roseobacter5 iso- lated from Indian Ocean deep-seawater36. Such roseobacters can comprise up to 20% of surface water bacteria37 and ~10% of bacteria in marine surface sediment38, and thus ...
Sponges and cnidarians are invertebrates, animals lacking a backbone, that are found in the ocean. Discover marine invertebrates and their environments, and learn about the characteristics of sponges and cnidarians. Related to this Question How do members of phylum porifera obt...
Bob is an ocean explorer who has traveled into the abyssal zone and has observed tube worms living around hydrothermal vents. What would be the ultimate source of nutritional energy in the food chain for these worms? A. Sulfur B. Heat C. Detritus D. Fish ...
