In the video of the estuary, the water level was rising because of new water flooding the area. Where was the water coming from?

• the ocean tides

• the river

• a lot of rain

In the estuary video, as the salty ocean water flooded the area, what adaptation is the most useful to the mangrove trees during the high tide?

• adaptation for sunlight

• adaptation to be flooded with water

• adaptation to live in sand

If you could look under the water at high tide, what types of animals would you see?

• animals like birds that only live on land

• animals like fish that live only in salt water

• animals like crabs that bury in the mud until the water is gone

In the estuary, plants and animals live only in certain parts of the estuary. For example, some live near the river and some live closer to the ocean. Some live in the middle where the water is brackish, a blend of salt and freshwater. Why is this?

• they like to live near their friends

• the water is too cold so they don't change

• they have specific adaptations for different types of water

• plants and animals live wherever they want to

Each aquatic biome has different levels of salinity. Match the biome to its salinity.

• blend of freshwater and saltwater

• freshwater biome

• highest level of salinity

• marine biome

• lowest level of salinity

• estuary biome

Each aquatic biome has different levels of salinity. Match the biome to its salinity.

• highest level of salinity

Each aquatic biome has different levels of salinity. Match the biome to its salinity.

• found wherever rivers meet the ocean

• marine biome

• large amount of water, near the coast to the very deepest parts

• freshwater biome

• water is moving like a river or still like a lake

• estuary biome

Each aquatic biome has different levels of salinity. Match the biome to its salinity.

• some plants have roots on the bottom of the pond, and their leaves float on the surface

• marine biome

• some plants have tiny air balloons to help them float at the surface for photosynthesis

• estuary biome

• some plants have adaptations so they can live in changing water levels

• freshwater biome

Each aquatic biome has different levels of salinity. Match the biome to its salinity.

• animals do have adaptations for removing salt from their bodies

• freshwater biome

• animals do not have adaptations for removing salt from their bodies

• marine biome

• some animals have adaptations for living in salty or fresh water

• estuary biome
