Taiga Biome What is a Taiga? The Taiga Biomes are Coniferous forests found in high northern latitudes. The taiga is home to numerous herbivorous animals, and small rodents. There are also carnivorous animals like bears, wolves, and foxes. Due to the climate, though, carnivorous diets are a bad way of obtaining energy as most energy is lost through trophic levels. Birds and smaller carnivores feed on the rodents, while the larger ones prey on the larger animals, like elk. What animals are
in the taiga? Larger animals like bears will eat a lot of food in the summer to gain weight and then hibernate all throughout the winter. Other animals have layers of feathers and fur to protect them from the cold. How do animals survive the climate? There is a relationship between organisms, populations, communities, ecosystems, and biomes. Multiple organisms of the same species in an area make up a population. All of the populations in the area make up a community. An ecosystem is all of the biotic and abiotic factors in the specific region. What are the classification levels? A division of the world's vegetation that corresponds to a defined climate and is characterized by specific types of plants and animals. What is a biome? The elements Carbon, Nitrogen, Oxygen, Hydrogen, and Phosphorous play a major role in every environment. They are the essential elements of life, and are constantly recycled. In the taiga, nutrient cycling is typically slow. The cold and dry
climate means that the decomposers and scavengers will
be less active, therefore the cycles take longer. Cycling of nutrients Evergreen trees can be found in the Taiga
Biome. These trees have the ability to maintain leaves throughout the year. This lets plants photosynthesize right away as the temperature begins to rise.

Trees that have needle-like leaves loses less water and is able to get rid of snow faster. These needle leaves have a coating which prevents evaporation. Plant Adaptations Human Involvement in the
Taiga -+ Organisms have relationships in biomes, like parasitism, mutualism, commensalism, competition, and predation. An example of parasitism would be aphids consuming plants. Predation would be a wolf hunting herbivores, like elk. Commensalism would be when an eagle creates a nest in a tree without harming it or benefiting it. Mutualism would be moss growing on a tree creating a home for the moss and protecting the tree. Competition would be like bears and wolverines both hunting rabbits. Relationship among organisms Humans destroy the Taiga almost everyday
Large scale tree cutting, road building, and mining has led to habitat loss. Destruction of the Taiga is harmful to humans and animals. A J-Curve occurs when the size of a population increases over a short amount of time. This usually happens when a population settles in an area where resources are not limited. J-Curve and S-Curve In an S-Curve, population starts to grow. As resources start to become limited, the population growth starts to decrease.
