Niche:
Energy Role
The Eastern Hemlock is a producer. It takes the sun's energy and turns that energy into food for other organisms. White-tailed deer eat the vegetation of the tree (the leaves). Mammals like mice, voles, and squirrels, eat the seeds.The Eastern Hemlock also provides food for the Eastern Cottontail Rabbits; they may eat the twigs.

Identification:
The white pine's cones are long and narrow. The needles are in clusters of five. White pines are different from other pines because the needles are in clusters of five and the red and pitch pine needles are in clusters of three. The white pine's bark is dark with deep cracks in it.

Energy Role:
The white pine is a producer. Young White pines are eaten by white-tailed deer and eastern cottontails. Squirrels, eastern chipmunks, voles, and mice eat the pine needles. The black-capped chickadee, pine warbler, yellow-bellied sapsucker, and the white-breasted nuthatch all eat the seeds from the pine cones.
