Biomes Every environment on Earth is distinct and is determined by biotic & abiotic factors They have typical: flora (plants) & fauna (animals) They have typical: temperatures, moisture, etc. Examples are: Tundra, Taiga, Deserts, Wetlands Deciduous Forests, Tropics, & Ocean

ECOSYTEM = Local BIOME = Similar ecosystems BIOSPHERE = ALL biomes (Living Environment)

Which biome? Which biome? Which biome?

What happens if there is a natural (or man-made) disaster in a biome?

Ecological Succession change in an ecosystem over time

Each biome has distinct Pioneer and Climax species. Pioneers Each biome has distinct Pioneer and Climax species.

The type of succession depends upon the biome The type of succession depends upon the biome. Tropical forests become tropical forests again, not deserts!
