Aquatic Biomes – Understanding Earth’s Water Ecosystems

What are aquatic biomes?

• Aquatic biomes are large ecosystems found in water environments, encompassing both freshwater and marine systems.

• Aquatic biomes are only found in deserts and dry areas.

• Aquatic biomes refer to mountain ranges and highlands.

• Aquatic biomes are types of forests located near the equator.

Which of the following is NOT a type of aquatic biome?

• Freshwater biome

• Marine biome

• biodiversity

• desertification

• urbanization

• deforestation

Marine biomes include rivers, lakes, ponds, and wetlands.

• True

• False

Name two main types of aquatic biomes.

• Freshwater biomes and marine biomes.

• Desert biomes and tundra biomes.

• Grassland biomes and forest biomes.

• Mountain biomes and savanna biomes.

What percentage of Earth's surface is covered by aquatic biomes?

• About 75%

• About 25%

• About 50%

• About 10%

Why are aquatic biomes important for maintaining biological diversity?

• Aquatic biomes provide homes to species ranging from tiny plankton to massive whales, sustaining the planet’s largest and most diverse populations of organisms.

• Aquatic biomes are important because they only support plant life and not animal life.

• Aquatic biomes are important because they reduce the amount of oxygen in the atmosphere.

• Fish and turtles (other acceptable answers: plankton, whales, coral, aquatic plants, etc.)

• Cacti and camels

• Lions and elephants

• Eagles and snakes

Which of the following is a contribution of freshwater biomes?

• A) Absorbing carbon dioxide and producing oxygen

• B) Supplying drinking water, irrigation for agriculture, and hydroelectric power

• C) Providing saltwater environments for coral reefs

• D) Regulating global climate
