Match the biome with the biome type.
Freshwater
Marine
Streams
Oceans
Ponds
Lakes
Coral Reef
Marshland
Rivers
Estuary
What type of organisms typically thrive in fast-flowing aquatic biomes such as streams?
Coral Reefs
Manta Rays
Benthic Macroinvertebrates
Seaweed
How does the water in streams typically become oxygenated?
Through photosynthesis
By flowing over rocks and plants
From rainfall
Via underground springs
Which factor determines how much life a river can support?
Amount of Oxygen
River width
Water flow speed
Distance from the sea
Why is dissolved oxygen important for organisms in a river ecosystem?
Provides buoyancy
Helps in digestion
Necessary for respiration
Needed for photosynthesis
What is the most common flora association in a pond biome?
Pine and Oaks
Algae and Lily Pads
Cactuses and Succulents
Seaweed and Corals
Which organisms are a vital part of the pond food chain?
Plankton, Insects and Fish
Lion, Zebra and Elephants
Whales, Coral and Seaweed
Shark, Turtle and Dolphin
What distinguishes a lake from a pond?
Lake has salt water
Pond is larger and deeper
Pond has more aquatic life
Lake is typically larger and deeper than a pond
How does depth affect temperature in a lake?
Depth has no impact on temperature
Deeper water is always warmer
There's no temperature difference
Deeper water is usually colder
What percentage of Earth's surface is covered by oceans?
About 70%
About 80%
About 50%
About 60%
What is the largest ocean on Earth?
Pacific Ocean
Atlantic Ocean
Indian Ocean
Arctic Ocean
What is the main source of food for coral in a reef?
Photosynthetic algae
Plankton
Seaweed
Fish
How are coral reefs affected by climate change?
Decreased salinity
Coral darkening
Increased coral growth
Coral bleaching
What is a key characteristic of a marsh biome?
Wetlands with grassy vegetation
Hot and dry climate
High mountainous region
Dense forest canopy
Why do marshes play an important role in the ecosystem?
They produce large quantities of oxygen
They act as a natural water filter
They are the main source of freshwater
They prevent desertification
What is an estuary?
A narrow inlet of the sea between cliffs
A body of water where freshwater meets the sea
An undersea mountain range
A large lake with salt water
What type of organisms thrive in estuaries?
Deep-sea organisms
Freshwater organisms
Desert organisms
Brackish water organisms
