Aquatic Biomes
What are the two types of aquatic biomes?
Freshwater & Marine (saltwater)
Where are tropical rainforests found?
Tropical rainforests are found near the equator.
What is the definition of a desert biome?
A dry area where less than 20 inches of rainfall falls per year.
What is the definition of a forest biome?
Dominated by trees
What is the definition of a grassland biome?
A large open area that has a lot of grass
What is the definition of a tundra biome?
Extremely inhospitable conditions and have a cold, frozen landscape
What % of the Earth's surface does aquatic biomes take up?
The aquatic biome is the largest of all the biomes, covering 75% of Earth's surface.
Where are rainforest biomes located?
Close to and around the equator
This biome receives very little precipitation. What physical adaptation helps many plants survive here?
Thick, waxy coverings and the ability to store water in stems or leaves.
3.
Large grazing animals such as bison or antelope live here. How do their movements benefit the ecosystem?
Their grazing helps cycle nutrients and maintain plant diversity.
Plants in this biome grow close to the ground and have short life cycles. Why is a short growing season a challenge for them?
They must sprout, flower, and reproduce quickly before the cold weather returns.
How do aquatic plants contribute to the oxygen supply in water?
Through photosynthesis, aquatic plants release oxygen into the water.
what percentage of the Earth is covered by rainforests
6%
What is the world's largest warm desert?
Sahara
What are the names of the types of forest biomes?
Boreal, temperate, tropical
What are the names of the grassland biomes?
Savannas and temperate grasslands
This biome is cold, dry, and has a layer of frozen soil called permafrost. How does permafrost affect plant growth?
It prevents deep roots from growing, so only low-growing plants like mosses and lichens can survive.
What is the primary difference between freshwater and marine biomes?
The amount of salt in the water; freshwater has less than 1% salt, while marine biomes have higher salt content.
What is the rainforest biome most well known for?
Known for having the highest biodiversity and its dense canopy of trees?
How much of Earth's surface does the desert biome cover?
1/5
How much of Earth's surface does the forest biome cover?
1/3
In this biome, rainfall is too low to support forests but high enough to avoid becoming a desert. How does this affect the dominant plant type?
It allows grasses to thrive, which are adapted to survive with less water than trees.
Where is this biome mostly located?
In the north and close to the poles
Why are wetlands considered vital ecosystems?
Wetlands filter pollutants from water, help control flooding, and provide habitats for diverse species.
Bonus question: Which country has the most rainforests?
Brazil
Bonus question: What country has the most deserts?
China (13)
What is the annual rainfall?
30-59 inches
What do animals eat in the grassland biome?
The grass
How does global warming affect the tundra?
Melting permafrost, due to climate change, is changing the landscape and impacts what plants can grow and, therefore, what animals can survive.
