Biomes #1 of 2

The biotic and abiotic factors that
determine a biome.
a large geographical area that has a certain
combination of biotic and abiotic factors.
The Earth’s diverse environments are grouped into 10
major terrestrial biomes (on the Earth’s surface).
Tropical Rain Forest, Tropical Dry Forest, Tropical Savanna, Desert, Temperate Grassland,
Temperate Woodland, Coniferous Forest, Temperate Forest, Boreal Forest (Taiga), and Tundra
Species vary in their adaptations to different conditions
(biotic and abiotic) in different biomes.
 Adaptation:
an inherited characteristic that increases an
organism’s biological fitness.
 Biological
Fitness: the ability to survive and reproduce.
The two main components of an area’s climate:
Temperature (avg. kinetic energy of air molecules)
Precipitation (amount of rainfall/snowfall)
A climatogram summarizes these two components
by graphing their average amounts each month.
 Independent
Variable (x) is months of the year
 One
Dependent Variable is precipitation (bar graph)
 One Dependent Variable is temperature (line graph)
 The
units for each variable can vary, so pay attention!
