Coniferous Forest

Coniferous forests have distinct seasons.

Limiting Resources in this ecosystem include:space top predators compete for territory oxygenat high altitudes, creatures must adapt to "thinner" air, such by producing higher than normal counts of red blood cellsheatthe extreme cold of a conifer forest winter saps vital body heat from animals; those who cannot insulate themselves will die

The conifer trees themselves provide a habitat for birds, insects, and smaller plants. Creatures use the trunks of the trees for shelter and predator protection.

In this food pyramid, the primary producers, plants, are consumed by the next trophic level, herbivorous animals. Energy is then passed on to the second trophic level as birds and small mammals eat the insects and rodents. At the highest trophic level are the top predators: wolves, raptors, and large cats.

Coniferous forests are typically found at northern latitudes.

What is it? The coniferous forest ecosystem is primarily found in the Northern hemisphere in the northern US, Canada, Russia, and northern Asia. It is bounded by the tundra ecosystem to the north and deciduous forests or deserts to the south. Conifer forests are characterized by warm summers (20* C) and harsh winters (-40* C), and receive, depending on the year, between 300mm-900mm of rainfall. They have distinct seasons, with about six months of frost or snow and six months of mild humidity. The conifer forest gets its name from the cone-bearing trees that carpet the land. These trees, such as pine trees, spruce trees, and fir trees, are the primary producers of the ecosystem along with small shrubs and ferns. Conifers have needle-like, waxy leaves that reduce surface area to guard against the cold, while still performing the necessary photosynthesis. The evergreen trees give the conifer forest ecosystem a high level of primary productivity year-round.

A stream habitat, found often in coniferous forests, consists of running fresh water from springs or melting snow. Fish and certain amphibians live in the streams, and insects use them as breeding grounds. Larger animals regulary stop by to drink the water.
