Biomes
- Biomes are regions made up of ecosystems with similar plant life and climate.
Rivers and Streams
- Rivers and streams, with high oxygen levels.
- Plants are limited to shorelines and slow-moving shallows.
Lakes and Ponds
- Lakes and ponds, with middling to very low oxygen levels.
- Plants grow along the shoreline or float in upper layers.
Wetlands
- Wetlands, such as swamps and bogs, that are wet most or all of the year.
- Waterlogged soils limit plant species.
Estuaries
- Estuaries, which are mixed fresh and salt water, where river meets ocean.
