Marine and Freshwater Biomes

What is the definition of salinity?

• the amount of salt dissolved in the water

• the temperature of the water

• the amount of oxygen dissolved in the water

• the amount of sunlight that reaches the water

Which aquatic biome has the highest salinity?

• marine biome

• freshwater biome

• desert biome

• tundra biome

What is the definition of marine?

• saltwater environments

• freshwater environments

• riding in a boat

• going to the aquarium

What type of salinity is in a marine biome?

• high salinity (high saltiness)

• low salinity (low saltiness)

• deep water

• shallow water

What type of water do most living things need to survive?

• freshwater

• saltwater

• cold water

• warm water

What are the water characteristics we studied when comparing aquatic biomes?

• salinity, dissolved oxygen, amount of sunlight

• salinity, dissolved saltiness, amount of trees

• dissolved oxygen, water freshness, amount of sunlight

• water pollution, water cycle, water frozen in ice

Why is the amount of dissolved oxygen important in water?

• aquatic organisms absorb oxygen from the water

• plants need oxygen to survive

• oxygen keeps the water clean

• oxygen keeps the water warm

Why is the amount of sunlight in water important?

• organisms can do photosynthesis with more sunlight in the water

• sunlight keeps the predators away

• sunlight is important for all living things

• sunlight keeps the water clean

What are the challenges of living in the marine biome?

• high salt content, storms, waves, little food in the open ocean

• more predators, cold water, high salt content

• hard to swim in the deep water

What types of adaptations are useful in the marine biome?

• able to filter out salt from the organism's body

• able to do photosynthesis

• able to swim in cold water

• able to get nutrients from the water
