Feb 17, 2023 · The ocean or marine food chain shows the relationship among the organisms living in the ocean. Since organisms live underwater, they differ from those dwelling in terrestrial environments. Food chains are different from one oceanic environment to another.
Oct 19, 2023 · On the ocean's surface waters, microscopic animals— zooplankton, which include jellyfish and the larval stages of some fish, barnacles, and mollusks—drift across the sea, grazing opportunistically. Larger herbivores include surgeonfish, parrotfish, green turtles, and manatees.

Organisms in food webs are commonly divided into trophic levels. These levels can be illustrated in a trophic pyramid where organisms are grouped by the role they play in the food web. For example, the 1st level forms the base of the pyramid and is made up of producers. The 2nd level is made up of herbivorous consumers and so on. On average, only 1...
Producers are described as autotrophic, which means they are able to make their own food. Just like producers on land, producers in the marine environment convert energy from the sun into food energy through photosynthesis. Phytoplankton are the most abundant and widespread producers in the marine environment. Other producers include seaweeds(a typ...
Consumers are described as heterotrophic, which means they are unable to make their own food and rely on consuming other organisms or absorbing dissolved organic material in the water column. Consumers are divided into herbivores and carnivores and are typically further divided into 1st, 2nd or 3rd level consumers. For example, many zooplankton in ...
Decomposers exist on every trophic level. They are mainly bacteria that break down dead organisms. This process releases nutrients to support the producers as well as the consumers that feed through absorbing organic material in the water column. This process is very important and means that even top-level consumers are contributing to the food web...
The effect of removing or reducing a species in a food web varies considerably depending on the particular species and the particular food web. In general, food webs with low biodiversity are more vulnerable to changes than food webs with high biodiversity. In some food webs, the removal of a plant species can negatively affect the entire food web,...
Each food chain starts with a primary producer or autotroph, an organism, such as an alga or a plant, which is able to manufacture its own food. Next in the chain is an organism that feeds on the primary producer, and the chain continues in this way as a string of successive predators.
May 2, 2023 · At AnimalWised, we discover the food chain of the ocean, learning how energy and matter pass between species to create some of the most diverse ecosystems on the planet. We also learn about how specific aquatic food chains exist within the context of a large marine ecosystem food web.
Oct 19, 2023 · A food chain is a top-to-bottom set of animals and plants. They are linked to each other because those on top eat those below. Level One: Photoautotrophs. The bottom level of the ocean's food chain is largely invisible. It is made up of billions of one-celled organisms, called phytoplankton.

How does a food chain work?
A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another. In a food chain, each organism occupies a different trophic level, defined by how many energy transfers separate it from the basic input of the chain.
