Welcome to our tundra food web chain page. Here we have broken down the tundra biome food web detailing which animals feed and prey on others with a single food chain diagram. If this is your first visit here you might want to read about what is the tundra biome. This is a handy chart in case you ever need to answer questions like "what do polar bears eat ?" or "what do arctic foxes eat?" .
The animals and plants of the tundra co-exist in a fine balance that is susceptible to changes in weather conditions, pollution and hunting. The habitat is made up of a number of highly adapted creatures that can survive the harsh conditions with adaptations that have evolved over thousands of years.
At the bottom level you will see plant life such as lichens and mosses which provide energy and sustenance for the herbivores such as muskox, caribou, snow geese and lemmings. Above those we find the first level of predators such as snowy owls, ermines and arctic foxes. This first level of predators are both hunters and opportunistic feeders and will readily consume meat from the carcasses of dead prey they may stumble across.
At the top of the arctic food chain we find polar bears and arctic wolves. These two animals have no natural predators as such although polar bears, arctic foxes, snowy owls and ermines will all feed on carrion ( decaying bodies ) of top level predators. However, they are not really actively preyed on.
Food web maps are rarely complete and this example of a tundra food web still has room for improvement. What we have tried to present here is a readable map that includes as many animals and plants as we could possibly fit on the diagram without it getting too large or complicated. Feel free to copy the map and use in your school projects or modify it to your own needs. If you would like to link back to use here at the tundra animals and plants site that would be nice too.
