Water CycleWhat are the three processes of the water cycle?

Cycles of Matter

Cycles of Matter

Carbon and Oxygen CyclesProducers, consumers, and decomposers all play a role in recycling carbon and oxygen.

Cycles of Matter

Nitrogen CycleIn 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.

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

Biomes

How would you fill in the Venn Diagram with what you know about temperate and tropical rain forests?

Biomes

Biomes

Rain-Forest BiomesRain forests are forests in which large amounts of rain fall year-round. Very little sunlight reaches the ground.

Tropical Rain ForestsWhat are the four distinct layers of the tropical rain forest?

Biomes

Grassland BiomesOn the world map, identify the continents which the Rhea, Cassowary, and Ostrich inhabit.

Biomes

Deciduous Forest BiomesMost of the trees in a deciduous forest have leaves that change color and drop to the forest floor each autumn.

Boreal Forest BiomesTree 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 BiomesAlthough the ground is frozen for most of the year, mosses, grasses, and dwarf willow trees grow here.
