Arctic Polar Bear Food Chain Biology Diagrams Arctic Food Chains and Food Webs 1. Arctic tundra Food Chain: Producers: Moss, algae, and lichen. Primary Consumers: Lemmings, caribou, and insects. Secondary Consumers: Arctic foxes and snowy owls. Top Predators: Polar bears and hawks. Example Food Chain: Sun โ Algae โ Lemming โ Arctic Fox โ Polar Bear. 2. Arctic Marine Food Chain
The polar bear is the world's largest species of bear and the largest land predator. There is a large difference in size between male and female polar bears with the male weighing anything from 350 to 800 kilograms. Females in contrast weigh less than half. As apex predators, polar bears are at the top the Arctic food chain. Only humans

Terrestrial Arctic Food Chain# Arctic Tundra Food Chain# The tertiary consumers, such as leopard seals, feed on the secondary consumers. Polar bears and Orca whales act as tertiary or apex (quaternary) consumers, depending on their participation in the food chain. Polar bears feed on and eat seals and fish, while Orca whales feed on small Explain that polar bears need sea ice for places to rest during hunting and to build dens for their young. Seals give birth and nurse their pups on the ice; the draw a diagram of a food chain from the Arctic coastal ecosystem. It should have at least 3 organisms. Draw arrows to show the transfer of energy from one level to the next. REACH
To understand what a food web is, we need to consider the concept of a food chain. Imagine a huge bowhead whale swimming in the Chukchi sea and consuming zooplankton in millions every day. Their connection can be represented in a chain โ a linear diagram showing the energy transfer between different organisms in an ecosystem. Polar bears are the top of the Arctic's land-based food chain. Their biggest threat to survival is not other species. Rather it is the changing environmental conditions brought on by climate

Download scientific diagram | Figure A1. Arctic food chain of the polar bear. from publication: Improvements to Elementary Children's Epistemic Understanding From Sustained Argumentation | The aim Polar bears form an extremely important role in the Arctic food web and food chain. A food chain is a diagram showing the linear transfer of energy between various organisms in an ecosystem A food chain only shows one direction of how energy is transferred. In nature, it is usually more complex as more than one animal might hunt a specific species. Food Webs The Arctic food web. Click for more detail. When many food chains are linked together they create a food web. Most animals have many food sources and also have many predators.
