Often asked: Which Life-form Is The Base Of The Food Chain In The Waters Around Antarctica Biology?

Many algae are found around Antarctica, especially phytoplankton, which form the basis of many of Antarctica’s food webs.

Which life form is the base of the food chain in waters around Antarctica?

These tiny creatures are called krill! They look like a miniature prawn. They form the basis of the food web in Antarctica. All animals depend on krill for their survival.

Which life form is the base of the food chain?

As you probably know, the organisms at the base of the food chain are photosynthetic; plants on land and phytoplankton (algae) in the oceans. These organisms are called the producers, and they get their energy directly from sunlight and inorganic nutrients.

What is the base of the food chain in the frozen seas?

Algae or phytoplankton form the base of the ocean’s food web. The sea’s ‘grass’ undertakes photosynthesis, turning sunlight and inorganic nutrients into food that can be eaten by organisms like zooplankton. Phytoplankton are microscopic but occur in large numbers in the water and are also attached to sea ice.

What is the Antarctic ecosystem?

Antarctica is a polar desert. Terrestrial life is limited to the very small. There are no trees or shrubs, so vegetation is mainly mosses, lichens and algae.

Where are blue whales on the food chain?

Penguins are carnivores; they eat only meat. Their diet includes krill (tiny crustaceans), squid and fish. Some species of penguin can make a large dent in an area’s food supply.

What do Antarctic herbivores eat?

The major proportion passes through the food web at the hub of which is the Antarctic krill (a key herbivore) and a variety of zooplankton. Predators of krill such as the baleen whales, crab eater seals, penguins, fish and squid are the primary predators of the food web.

Can you eat fish from Antarctica?

“You can fish, but only with a scientific collection permit. All of the animals of the Southern Ocean are protected under the international Antarctic Treaty. So, even though there are species of cod that are edible, they are protected and can’t be caught, unless for scientific study.”

Which trophic level forms the base of a food chain?

At the base of the food chain lies the primary producers. Primary producers are principally green plants and certain bacteria. They convert solar energy into organic energy. Above the primary producers are the consumers who ingest live plants or the prey of others.

What is food chain short answer?

A food chain describes how energy and nutrients move through an ecosystem. At the basic level there are plants that produce the energy, then it moves up to higher-level organisms like herbivores. After that when carnivores eat the herbivores, energy is transferred from one to the other.

What is food chain for Class 3?

Answer: A food chain is a sequence of events where one organism eats another, and the energy is transferred on. Explanation: The food chain is the order of events in the ecosystem, where the energy and nutrients are transferred from one organism to another.

Is food a chain?

food chain, in ecology, the sequence of transfers of matter and energy in the form of food from organism to organism. Food chains intertwine locally into a food web because most organisms consume more than one type of animal or plant.

What is the food web in the tundra?

Food web are caribou, pika, Arctic hare, musk ox and insects. Secondary consumers eat herbivores. They are at the third trophic level. Secondary consumers in the Arctic Tundra.

What is eaten by zooplankton?

Zooplankton are small, floating animals. They include fish larvae, jellyfish, microscopic copepods and small, bottom-dwelling animals. They drift through the ocean; zooplankton eat phytoplankton, which transfers the energy phytoplankton create with photosynthesis to the next level of the fish food chain.

Why Is It Important To Take Enviromental Biology?

Environmental science is important because it enables you to understand how these relationships work. For example, humans breathe out carbon dioxide, which plants need for photosynthesis. Plants are sources of food for humans and animals. In short, organisms and humans depend on each other for survival. Contents1 What can you do with environmental biology?2 What […]

Why Is Incest Bad Biology?

Inbreeding results in homozygosity, which can increase the chances of offspring being affected by deleterious or recessive traits. This usually leads to at least temporarily decreased biological fitness of a population (called inbreeding depression), which is its ability to survive and reproduce.
