| a kind of plant and animal community that covers large geographic areas.climate is a major determiner of the biome found in a particular area | biome |
| a broad band of mixed coniferous and deciduous trees that stretches across nother america(and also Europe and Asia);its northermost ewdge is integratedwith the artic tundra | boreal forest |
| last stage of succession; a relatively stable, long-lasting, complex, and interrelated community of plants, animals, fungi, and bacteria | climax community |
| a tropical, shallow-water, marine ecosystem dominated by coral organisms that produce external skeletons | coral reef ecosystem |
| a biome that receives less than 25 centimeters of precipitation per year | desert |
| aquatic vegetation that is rooted on the bottom but has leaves that float on the surface or protrude above the water | emergent plants |
| marine ecosystems that consist of shallow, partially enclosed areas where freshwater enters the ocean | estuary |
| the upper layer in the ocean where the sun's rays penetrate | euphotic zone |
| aquatic ecosystems that have low amounts of dissolved salts | freshwater ecosystem |
| areas receiveing between 25 and 75 centimeters of precipitation per year. grasses are the dominant vegetation, and trees are rare | grassland |

| region with rooted vegetation in a freshwater ecosystem | littoral zone |
| marine shoreline ecosystems dominated by trees that can tolerate high salt concentrations | mangrove swamp ecosystem |
| area of grasses and reeds that is either permanently flooded or flooded for a major part of the year | marsh |
| a broad band of mixed coniferous and deciduous trees that stretches across northern America(and also Europe and Asia);its northernmost edge is integrated with the arctic tundra | northern coniferous forest |
