Major Water Biomes
This percent of the Earth is covered by ocean.
What is 70%?
This term describes a large area with similar biotic and abiotic factors.
What is a biome?
True or False: The abyssal zone is noted for its warm temperatures created by escaping gases.
False
True or False: Ponds form where freshwater and saltwater meet.
False
This is formed when biotic and abiotic factors interact.
What is an ecosystem?
This biome has a salinity of 3 to 3.37%.
What is the marine biome?
This marine biome consists of shallow waters between the littoral zone and the edge of the continental shelf.
What is the sublittoral zone?
This zone does not contain enough minerals in the water to support organisms.
What is the abyssal zone?
True or False: Deep lakes have zones like the marine biome.
True
This determines the different aquatic biomes.
What is the salinity of the water?
This biome has a salinity of 0.005% or less.
What is the freshwater biome?
This living organism supports most life found in the sublittoral zone.
What is algae?
Light cannot penetrate the ocean below this depth.
What is 200 meters?
This term refers to the amount of suspended material in a liquid.
What is turbidity?
This is the term for free-swimming organisms.
What are nekton?
This is the largest biome on earth.
What is the marine biome?
This marine zone is divided vertically by depth into three additional zones.
What is the pelagic zone?
Food in this zone is primarily decaying organic matter.
What is the bathyal zone?
These are the two types of freshwater biomes.
What are standing water and running water?
This is the term for bottom-dwelling organisms.
What are benthos?
These are areas of freshwater that flow into oceans.
What are estuaries?
This marine zone includes the open waters past the sublittoral zone.
What is the pelagic zone?
This is the zone of the ocean lower than 2,000 meters.
What is the abyssal zone?
Name two of the three factors that affect freshwater biomes.
1. temperature
2. current
3. turbidity
These organisms manufacture food from chemical energy.
What are chemosynthetic organisms?
