Biomes
Enduring Understandings:
Essential Questions:
 Earth’s biomes result from the topography,
temperature, precipitation and soil type present in an
area.
 The type of life (biotic factors) supported in an area is
a result of the abiotic factors of the area.
 The populations and the abiotic factors interact to
keep a balance in an ecosystem.
 The balance of an ecosystem can be effected by
natural disasters and man-made activities.
 Which biome is formed from a specific combination of
abiotic factors?
 How are organisms adapted to their specific biome?
 How do the interactions between the organisms keep a
biome (ecosystem) balanced?
 What might be a possible effect of natural disasters and
man-made influences on a ecosystem?
