Harp Seal Food Chain Biology Diagrams Food chain in the arctic described with examples and a simple diagram. Physics. Why Does Water Expand When It Freezes; Gold Foil Experiment; (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 fishes and larger fishes like whales and seals 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.
An arctic tundra food chain: Moss and Lichens (Producer) โ Arctic Hare (Primary Consumer) โ Arctic Fox (Secondary Consumer) โ Polar Bear (Tertiary Consumer) Diving into Food Webs. While food chains provide a clear, linear model of energy flow, nature is far more complex. Food webs present a more accurate picture, showcasing the The Arctic apex predator that is the polar bear. As apex predators, polar bears are at the top the Arctic food chain. Only humans pose a threat to this massive and majestic species. But all it takes is one look to understand why so many people book Arctic trips in the hope of spotting a polar bear in the wild. 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
Arctic Food Webs Biology Diagrams
In other seasons when the bear eats mainly berries, the bear is lower on the food chain than salmon. Isotope ratios can be used to trace seasonal and spatial differences in diet. This diagram below shows the full food chain for bears during salmon season when the bears are carnivorous, starting with algae at the base of the salmon food chain. allows even giant polar bears to survive in a place where the sun doesn't strike their fur for months in midwinter. Food webs are made of interconnected food chains. At each link in the food chain energy is lost as it passes from one organism to another. Roughly only 10% of the energy is passed along. The remaining 90% is lost to heat. 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
