The Canadian Boreal Forest Food Chain.


(Organisms on different levels of the same food chain... kinda.) It required a few more pictures to tie it all together.

Alright, I'm going to attempt to explain one of Canada's food chain, because I discovered I have enough pictures for it. Some of them are a bit blurry because I took them from far away... I didn't really want to get that close to the animals... and most of then are located at my cottage in Parry Sound, Ontario, Canada, or the Yukon and Northwest Territories. These animals span all across Canada, it's the same food chain pretty much everywhere regarding large wild animals.

You should know that this food chain doesn't really have levels, it's more of a BIG mindmap. Animals are known to kill other animals all over the food chain, near the bottom, near the top,  but do not necessarily eat them for nutrients. They're just protective or have violent natures. The food chain also has animals that may have the same predators, but the 2 predators also hunt eachother regularly, to the food chain can change. There isn't really a dominant predator, or top of the food chain, so to speak.

So this is the Boreal Forest, specific to Canada and parts of Russia. Unlike the Deciduous forest, it does not usually contain pine trees. It houses all of the animals (although some travel in and out) that you're about to see, and provides a food source for specifically the rabbit and the moose.
The rabbits also feed off of the humans crops and things planted in the forest, and other green fertile things they can eat.. they're just kind of there as a source for the foxes.

This next animal, the fox, preys primarily on small animals such as rabbits and rodents that live in the forest.


Then comes the moose... Moose live in the boreal forest and gain nutrients by eating literally anything green within it. Moose also eat roots and strip the bark off trees (which is why I've included the picture of tree bark above.) They keep to themselves, which is why I kind of isolated this one, (it doesn't eat rabbits or foxes) but provide food to bears and wolves, yet more than usually kills them. They're strong forces against wolves, and the predators will not attack unless a single moose is by itself and there is a very large number of wolves ready in the pack.



The next two animals are constantly battling for dominance in the food chain and will eat anything above for their main diet (except the plants) ; The multiple types of wolves and the different types of bears.



The Grey Wolf (top far left) was taken at a hunting display in the Yukon. They will eat anything they can bring down in large groups, even bears, which is why the top of the chain is unclear. The arctic wolf travels through both the tundra and the boreal forest, and also preys on smaller animals individually (although it's rare that they're by themselves) and larger animals in packs.



Finally, there's the bears. the black bear at the dump at my cottage and the brown bear on display in the Yukon are protective of their offspring and will attack anything they deem threatening. Between wolves and bears, bears are probably more dominant in the food chain. Polar bears often venture into the northernly territories (if anyone knows anything about Canadian geography) but do not live in the forest. It's not natural.

So... that's the food chain! It was kind-of hard to isolate a single part of it, so I wound up covering most of it. And I know, Mrs. P, that you're only counting 5 pictures for points, but otherwise I wouldn't have been able to really put it together :)

  1. Why do you have pictures of dead animals that were hunted? Not appropriate =(
