Biomes: - Large terrestrial regions on earth with similar climate, soil, and life forms.
Permafrost - Permanently frozen ground year round
*Taiga - Covers 11 % of earths land - 1/3 of all the trees (not species of trees) on earth.
*Temperate Deciduous Forest -
Deciduous - Trees with broad leaves that loose their leaves in the winter.
*Tropical Rain Forest - Most productive biome on earth.
*Desert - Least productive biome on earth.
Allelopathy - Release of toxins by plants (leaves and roots) to inhibit growth of other plants nearby.
Rain Shadow Deserts - Formed by climate patterns and mountains. Mojave and Sonoran Deserts are examples.
Aquatic Ecosystems: - Aquatic ecosystems occupy about 3/4 of the earths surface. The two main types are freshwater and saltwater habitats.
Water Column - Most aquatic life lives in the water column (good swimmers).
Plankton - Small floating organisms like algae (poor swimmers).
Benthos - Organisms that live on the bottom of the body of water
*Wetlands - A transition between the land and water
Marsh and Swamp - Shallow bodies of water
*Creeks and Rivers - The least productive aquatic ecosystem. They are flowing water
*Ponds and Lakes - They are standing water
*Estuaries - Occur where fresh (Rivers) and saltwater (Oceans) meet. They are the most productive ecosystem.
Salt Marsh - Salt water with predominantly grasses.
*Oceans - Deep saltwater that are influenced by tides and currents.
El Nino - unusually warm equatorial waters near Christmas time.
La Nina - unusually cold equatorial waters near Christmas time.
