Primary food source in the open sea is?

Changes in ocean circulation and water temperature significantly affect microscopic plants called phytoplankton that form the basis of the food chain in the open sea. Whales, shrimp, snails, jellyfish and many fishes depend on phytoplankton as a primary food source.

What is a food source for the open ocean?

Open oceans are home to a variety of living things – from microscopic plankton to gigantic fish and mammals. Tiny plant organisms called phytoplankton drift in surface waters and convert sunlight into food, which is eaten by masses of tiny animals called zooplankton.

What is the main food source in the deep sea?

The three main sources of energy and nutrients for deep sea communities are marine snow, whale falls, and chemosynthesis at hydrothermal vents and cold seeps.

What are the primary producers in the open ocean?

The principal marine primary producers are cyanobacteria, algae and marine plants. The oxygen released as a by-product of photosynthesis is needed by nearly all living things to carry out cellular respiration. In addition, primary producers are influential in the global carbon and water cycles.

What is a primary producer in the sea?

macro- (seaweeds) algae, green plants, or photosynthetic. blue-green or purple bacteria. These organisms produce. ecosystem food that supports the food chain, hence they. are referred to as primary producers.

What is the open ocean called?

The pelagic zone, also known as the open ocean, is the area of the ocean outside of coastal areas. Here you will find some of the biggest marine life species.

What lives in the open ocean?

mollusks such as octopus and squid as well as many mammals including species of whales and dolphins. plankton. Whales, sharks, octopus, dolphins, sea cucumbers, squids.

What is the top of the food chain in the sea?

The orca, or killer whale is at the top of the marine food chain. In spite of the fact that they are called “killer whales,” orcas are actually dolphins. Orcas have 4-inch long teeth that they use to feast on other ocean animals, which can include seals, sea lions, sharks, seabirds, fish, and even whales.

What is the food chain in the sea?

Open Ocean Food Chain:

The first consumer is zooplankton that eats the phytoplankton. The second consumer consists of large fish, jellyfish, or crustaceans that eat the phytoplankton. The third consumer consists of larger predators that eat the fish, jellyfish, or crustaceans, such as sharks, squid, and dolphins.

What is found in deep sea?

The abyssal plain is the relatively level deep seafloor. It is a cold and dark place that lies between 3,000 and 6,000 meters below the sea surface. It is also home to squat lobsters, red prawns, and various species of sea cucumbers. For these creatures food is scarce most of the time.

Is the primary producer?

The primary producers include plants, lichens, moss, bacteria and algae. Primary producers in a terrestrial ecosystem live in and around organic matter. ... They take nutrients from organic matter left in the soil by decomposers and transform them into food for themselves and other organisms.

What are the primary consumers?

Primary consumers make up the second trophic level. They are also called herbivores. They eat primary producers—plants or algae—and nothing else. For example, a grasshopper living in the Everglades is a primary consumer.

Are zooplankton primary producers?

Phytoplankton are the primary consumers of the ocean; Zooplankton are the primary producers of the ocean. ... Zooplankton are at the base of the aquatic food web (primary consumers) so they would eat Phytoplankton that gets their energy directly from the sun.

What is the primary product of primary production?

The main products of primary production are carbohydrates. How do scientists measure primary production? Scientist measure primary production by turning the amount of carbon into living things. The more carbons per square, the more productive the ecosystem is.

What is primary production and examples?

The primary production stage of the supply chain encompasses agricultural activities, aquaculture, fisheries and similar processes resulting in raw food materials. ... Examples of primary production activities are: farming, fishing, livestock rearing and other production methods.

Who are called primary producers?

Plants are called primary producers because plants produce their food themselves through the process of photosynthesis.
