Biotic Factors
Biotic Factors
The large predators like wolves and lynx eat the smaller predators like birds, skunks, owls, weasels and foxes.
Moose, elk, insects, birds and small rodents eat the evergreen trees, shrubs, grass, ferns and moss.
The worms, bacteria in the soil, worms, protozoans and fungi serve as the decomposers.
Abiotic Factors
Use of the Coniferous Forest
The use of the Coniferous Forest is endless because it is such a large biome. Most of the forests are commercially managed. Examples of commercially managed Coniferous Forests are all the National Parks all over the United States. These forests also provide a beautiful landscape to go and hike or have a picnic.
Impact on the Coniferous Forest
Humans have a big impact on these forests. The negative impacts are the logging businesses. They are taking the trees in the forests and destroying habitats that were originally there. By taking these trees they are also taking away of oxygen producers. This business also contributes to global warming. A positive effect humans have is that we try our hardest to keep the forest in good shape. We pick up litter and we help with over population by having certain times when you can hunt certain animals.

Coniferous Forest
cone-bearing, needle-leaven or scale-leaved evergreen trees
pines, spruces, firs, larches
low shrubs, herbs, many types of moss, liverworts and lichens
lakes, bogs and rivers

Food Web
Long cold winters with temperatures ranging from 15degreesF to -5degreesF. The cold air is unable to hold much more water vapor so the snow doesn't melt until spring.
With long winters and short summer, plants only have about a 3 month growing period.
During the fall there is moderate to high precipitation. The annual precipitation is 300 to 900 mm. The temperatures start to get colder and the plants lose their leaves.
During the summer the temperature ranges from 40 to 70degreesF. The summer is very short and only consists of 75 to 150 days.
Many of the vegetation in a Coniferous Forest are producers; organisms that capture energy (sunlight) and use it to make organic molecules. Within this group of producers some of the plants are autotrophs; these plants are able to make their own food (photosynthesis).
Many, if not all, of the animals in a Coniferous Forest are consumers. This means they cannot manufacture their own food. All consumers are separated into four different groups: herbivores, carnivores, omnivores, and detritivores
