Biotic an Abiotic Factors
-Abiotic: snow, dirt, mountains, rivers, and rocks
When the water is frozen, trees cannot use it for photosynthesis.
In the Taiga biome, temperature can reach as low as -80 degrees. This makes it difficult for most animals to live here.
In the summer temperature can reach above 100 degrees. For animals that have thick fur for the freezing winters, it isn't exactly ideal.
Variations of three organisms
-Otters: some otters have thicker and darker fur if the water they live near frequently freezes.
-Wolves: some wolves may be white to stalk prey in the winter, and some may be smaller or larger.
Tolerances of three organisms
- Black Bear: several layers of fur allow the bear to stay warmer than others
-Canadian Lynx: the lynx is silent, but not very fast so it must sneak up on its prey
Adaptation of three organisms
-Ermine: dark in the summer, white in the winter.
-Humans: wear heavy, warm clothing.
