This Arctic
food web shows how producers, predators, scavengers and parasites
are linked to the Arctic hare (Lepus arcticus).
The arrows show the direction of energy flow.
The plant producers are:
- Arctic willow (Salix arctica)
- purple saxifrage (Saxifraga oppositifolia)
- grass (species not identified)
- sedge (species not identified).
Predators include:
- Inuk hunter (Homo sapiens)
- Arctic wolf (Canis lupus)
- Arctic fox (Vulpes lagopus)
- ermine (Mustela erminea)
- Snowy Owl (Bubo scandiacus)
- Gyrfalcon (Falco rusticolus)
- Rough-legged Hawk (Buteo lagopus).
Two general parasites, fleas and mosquitoes (species not
identified), and decomposers in the form of blow flies (Boreelus
atriceps), also derive energy from the Arctic hare. |
