Lewis and Clark Animal Discoveries. The Lewis and Clark expedition resulted in the discovery or observation of more than 300 plants and animals. Below is a sampling of those discovered. All excerpts are taken from the actual journals of Lewis and Clark during their three year expedition. Grizzly Bear.
A biome /ËbaÉªoÊm/ is a formation of plants and animals that have common characteristics due to similar climates and can be found over a range of continents.iomes are defined by climate regimes and biogeography. A 1978 study on North American grasslands found a positive logistic correlation between evapotranspiration in mm/yr and above-ground net primary production in g/m 2 /yr.
Background Information A biome is a geographic area with certain unique characteristics and unique animal and plant communities. Biomes contain smaller ecosystems. Rainfall and temperature, as well as species of organisms, are the main factors that determine the type of biome found in a specific region.ey concepts include a) differences between ecosystems and biomes; b) characteristics of land, marine, and freshwater ecosystems; and c) adaptations that enable organisms to survive within a specific ecosystem.
