Sand Waves in the Desert
Species that were unable to adapt to the changing environment and competition from other life forms became extinct. Cells within colonies became increasingly specialized, resulting in true multicellular organisms.

Ecosystems are composed of a variety of abiotic and biotic components that function in an interrelated way. The structure and composition is determined by various environmental factors that are interrelated.
Exploring Nature in Mountains
The atmosphere also retains heat during the night, thereby reducing the daily temperature extremes.These currents help to moderate the differences in temperature between winter and summer in the temperate zones.
