2 Oh, Deer!!!!! Game!!!!!!!Living things depend on each other and on the nonliving things in their environment in order to thrive.Changes in the environment cause changes to living organisms.
3 Habitat The specific environment where an organism lives. meadow pond treeriversoil
4 SpeciesA group of organisms that can produce offspring that are like themselves
5 PopulationAll the organisms of the same species that live in the same area at the same time.
6 CommunityPopulations of different species that live in the same area at the same time.
7 Living things: Nonliving things: Ecosystem + = Ecosystem: all the populations of organisms and theNonliving things in an environment, and the interaction amongthem.Nonlivingthings:SoilWaterOxygenCarbon DioxideSunlightLiving things:PlantsAnimals+=EcosystemCan be small (pond).Can be large (desert).
9 BiomeOne of the six major land areas of the world that is home to specific plant and animal populations and is defined by its climate.
10 Tropical Forest Warm temperatures Rainy climate Many trees and other plantsMany animalsHave you seen Tarzan?
11 Desert Very little rainfall or snowfall Can be hot temperature or cold temperatureFew plants or animalsHave you seen Rango?
12 Grasslands Mostly flat land Covered with tall grasses Few trees Warm climateNot as dry as desertHave you seen Dances with Wolves?
13 Deciduous Forest Has four seasons Warm summer and Cold winter Trees lose their leaves in autumnMany plants and animals
14 Taiga Evergreen forest: fir and pine trees Long, cold winter Short, mild summerElk, moose, bears, are some animalsHave you seen Open Season?
