Pin on Study Bio Biology Diagrams 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. 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.
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.

household items that are the size of a baby polar bear. Learn more about moms and baby polar bears here: Mom and Cubs Mini Poster Grades 3-5: The Arctic food web is very unique because it starts with small aquatic plants called ALGAE. Even though polar bears don't eat the algae, they need it because it feeds other animals in the food chain! 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.
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 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

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
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
