Section 2.4 - Earth's Biomes Flashcards
Earth’s 6 biomes:
Tundra, Taiga (boreal forest), Deciduous Forest, Grassland, Rain Forest, and Desert
______:
- permafrost, bitter cold, and high winds means no trees or tall plants
- little annual rainfall, but accumulation on top of permafrost
- mountain tops around the world can be alpine ______
Tundra
______ (boreal forest):
- large terrestrial biome
- dominated by cone-bearing, evergreen trees (coniferous)
- adapted to heavy snowfall
Taiga
______ forest:
- mid latitudes, with enough moisture to support trees
- ______ trees drop their leaves in the winter
Deciduous
______:
- deep, rich topsoil means a lot of conversion to agriculture
- seasonal drought, occasional fires and grazing by large mammals prevents shrub and tree establishment

- closed tree canopy
- pronounced vertical stratification (layering)
Rain
______:
- sparse rainfall
- extreme temperatures (hot and cold)
- organisms adapted to CONSERVE water
- many protective adaptations of plants to deter herbivory (the eating of plants)
Desert
A ______ is a large geographical region with a specific climate that the plants and animals that inhabit it are adapted to
Biome
Cells and biomes are ______ systems that exchange matter and energy with their surroundings
Open
Dividing Earth into biomes helps scientists to study and understand the Earth and ______ between the living and non-living components of each ______ and how the biomes ______ with one another, it also makes it easier for scientists to predict how different groups of organisms may be affected by ______ that may occur in a region.
