Carnivorous plants - like all plants - can make food from the sun's energy and carbon dioxide in the air and water from the ground. The insects that the carnivorous plants eat are devoured not for food but for the minerals they provide.

Fir
Balsam FirAbies balsamea (L.) Mill.
Balsam fir is a medium-sized (>25 m) tree that is widespread throughout Canada. Young bark yields conspicuous resin blisters. The resin from this tree was combined to form a compound called "Canada balsam", which was once used to mount specimen samples on microscope slides. It is the provincial tree of New Brunswick.
Grand FirAbies grandis (Dougl.) Lindl.
Grand fir is a giant (>70 m) tree. Its needles are very distinctly two-ranked. First Peoples chewed the "sweet" pitch of grand fir for enjoyment.
Pacific Silver FirAbies amabilis (Dougl.) Forbes
Pacific silver fir is a large (>45 m) tree. It takes its name from the shining silvery undersides of its needles. It is one of the very slow-growing species found in the subalpine habitat.
Subalpine FirAbies lasiocarpa (Hook.) Nutt.
Subalpine fir is a medium-sized (>30 m) tree. Like all other true firs, its foliage is very aromatic and its cones are upright with deciduous scales, bracts and terminally winged seeds. These seeds are an important food source for squirrels, especially in the autumn.
