| Estuary at high tide | Salty ocean water is pushed into it |
| Factors that determine which plants and animals live in an aquatic biome | Amount of salt, temperature, oxygen, sunlight, water pressure |
| Two major aquatic biomes | Marine and freshwater |
| Deep in the ocean, where there is no sunlight, there are | No plants and some animals |
| Deep lakes contain | Fewer plants and more animals |
| Two plants found in still, fresh water | cattails and lillies |
| Two animals found in still, fresh water | carp and turtles |
| Cattails and turtles cannot survive in fast-moving water | Lack of nutrients and inability to withstand strong currents |
| If a freshwater river that emptied into an ocean bay began to dry up | Animals that are adapted to salt water would thrive while those better adapted to fresh water would die |
| Fish that are the best swimmers would be found | In an estuary because water frequently comes from different directions |
| People that pollute | destroy the environment for those that do not pollute |
