Cycles of Matter
Water Cycle
What are the three processes of the water cycle?
Cycles of Matter
Carbon and
Oxygen Cycles
Producers,
consumers, and
decomposers all
play a role in
recycling carbon
and oxygen.
Cycles of Matter
Nitrogen Cycle
In the nitrogen cycle,
free nitrogen from the
air is fixed into
compounds.
Consumers can then
use these nitrogen
compounds to carry
out their life
processes.

Biomes
Desert
Organisms must be adapted to little or no rain and to extreme
temperatures to be able to live in the desert.

How would you fill in the Venn Diagram with what you know about
temperate and tropical rain forests?
Biomes
Rain-Forest Biomes
Rain forests are forests in which large amounts of rain fall year-round.
Very little sunlight reaches the ground.
Biomes
Tropical Rain Forests
What are the four distinct
layers of the tropical rain
forest?
Biomes
Grassland Biomes
On the world map, identify the continents which the Rhea, Cassowary,
and Ostrich inhabit.
Biomes
Deciduous Forest Biomes
Most of the trees in a deciduous forest have leaves that change color
and drop to the forest floor each autumn.
Biomes
Boreal Forest Biomes
Tree species in the boreal forest are well adapted to the cold climate.
Because the water is frozen for much of the year, coniferous trees have
thick, waxy needles to prevent water loss.

Tundra Biomes
Although the ground is frozen for most of the year, mosses, grasses, and
dwarf willow trees grow here.
Biomes
Mountains
Mountains are not part of any major biome.

Biome Climates
An ecologist collected climate
data from two locations. The
graph shows the monthly average
temperatures in the two locations.
The total yearly precipitation in
Location A is 250 centimeters. In
Location B, the total yearly
precipitation is 14 centimeters.
