Arctic Narwhal Biology Diagrams Food Web on The Ice Cover of Arctic. Besides the lands surrounding the Arctic circle, the Arctic Ocean also remains covered in an ice cover. However, this cold barren-looking ice stretch is not devoid of life. On the contrary, it supports a whole chain of the food web. When summer approaches, the sea ice starts melting.
Narwhals play a crucial role in their Arctic ecosystem. They are a key part of the food chain, serving as both predators and prey. As predators, they help control the population of their prey, such as fish and squid. As prey, they provide food for polar bears and killer whales. Additionally, their feeding habits can influence the distribution of nutrients in the water, which can impact other
Arctic Food Web: Everything You Need To Know Biology Diagrams
Whales, like the narwhal, are at the top of the food chain and have an important role in the overall health of the marine environment. Narwhals are also culturally important to indigenous communities in the Arctic. Like polar bears, the narwhal depends on sea ice for its existence and can be directly impacted by climate change. An integral food chain link among them is the Arctic cod, which links the underwater web with the one on land since it is eaten by ringed seals and ivory gulls. Other Arctic whale species, like the bowhead whale, beluga, and narwhal, mostly eat krill and fish. The Land Food Web. On land, the Arctic wildlife is represented by a variety of Arctic cod, another staple in the narwhal's diet, thrives in the icy waters and is a crucial link in the Arctic food web. This species is not only important for narwhals but also for other marine predators, underscoring its ecological significance. The cod's ability to survive in sub-zero temperatures makes it a reliable food source
Narwhals have several natural predators, including polar bears, walruses, and killer whales (orcas). Polar bears are the largest land predators and are known to hunt narwhals when they surface for air. Walruses also prey on narwhals, particularly young calves, by attacking them from below. Killer whales are the most significant natural predators of narwhals, and their presence can What Are the Predators of a Narwhal? Although narwhals are amongst the top animals of the food chain in the polar region, they still have predators. The main predators of narwhal are orcas, polar bears, and humans 18 (source: Wikipedia). As a result of declining summer sea ice in the Arctic, some predators have higher access to narwhals.

Polar bears are the top of the Arctic's land-based food chain. Their biggest threat to survival is not other species. 12 Curious Narwhal Facts. 9 Beguiling Facts About Belugas. 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.
