Document Summary

Adaptation: a characteristic that improves survival or reproduction. Natural selection: individuals with certain adaptations tend to survive and reproduce at a higher rate than other individuals. Population: group of individuals of a species that are living and interacting in a particular area. Community: association of populations of different species in the same area. Biomes large-scale biological communities shaped by the physical environment, particularly climate characterized by the major plant life within them. We use plants because they can"t move so they must face their environment and animals are to hard to find and categorize. Deciduous trees loose their leaves and live in seasonal climates with fertile soil. Grasses grow from the base, moist, seasonally warm/cool climate. Evergreen needle bearing, infertile soil, moist, seasonally warm/cool. Forbs non-woody plants that aren"t grasses (ex. Shrubs that tough, leathery leaves and grow close to the ground. Convergence evolution of similar growth forms among distantly related species in response to similar selection pressures.
