1.1 Aquatic Biomes (Freshwater) + The extra stuff from bio Flashcards
How many types of biomes are there?
2
What are the 2 types of biomes?
1) Terrestrial Biomes
2) Aquatic Biomes
Aquatic Biomes
water biomes that are differentiated by salt water, dissolved oxygen, and nutrient concentration and light penetration
What are the aquatic biomes
lakes, wetlands, streams and rivers, estuaries, intertidal zones, ocean pelagic zone, coral reef, marine benthic zone
what are the different types of aquatic biomes
marine and freshwater
Are Aquatic Biomes diverse
no
How many parts is the ocean made of?
5
What are the 5 parts of an ocean
1) Photic zone
2) Aphotic Zone
3) Pelagic Zone
4) Abyssal Zone
5) Benthic Zone
Pelagic Realm
depth of ocean (from surface to bottom ) this includes the Photic and Aphotic zones
How many zones is the Pelagic Realm split into
2
What are the 2 zones the Pelagic Realm is split into
Photic Zone
Aphotic Zone
Benthic Realm
bottom of any aquatic biome
What are organisms that live in the Benthic Realm called
benthos
Photic Zone
the part of the Pelagic Realm where light penetrates
What is the only place in the ocean where photosynthesis can occur?
Photic Zone
What is the first part of the Pelagic Realm
Photic Zone
Aphotic Zone
the part of the pelagic realm where light does not reach
How do organisms that live in the aphotic zone survive
by eating chemoautotrophs or dead organisms from the photc zone
Continental Shelf
where water is covering the edge of a continent
Intertidal Zone
zones in which organisms are sometimes in water, sometimes in air
What organisms live in intertidal zones
mollusks, snails, starfish, clam, etc.
Coral Reef is a(n) ____
animal
what is a coral reef based on
calcium deposits
What is the temperature of Coral reefs
generally warm
Are Coral Reefs diverse
yes SUPERRRR
are Coral Reefs in shallow or deep water
shallow
Is a Coral Reef a Biome
yes
Where are coral reefs located?
in the photic zone of tropical waters above continental shelves
What is the base of a coral reef
cindarians that secrete a hard external skeleton and algae crusted with calcium carbonate
Wetlands
zones that are either submerged in water or completely submerged
How many types of wetlands are there
2
What are the 2 types of wetlands
Marine Wetlands and Freshwater wetlands
Estuary
where fresh water meets salt water
Are estuaries diverse
yes
Estuaries are a ______ for birds and fish
breeding ground
Freshwater biomes
standing fresh-water biomes
how many types of freshwater biomes are there
2
what are the two types of freshwater biomes
standing water and flowing water
what is more nutrient filled deep freshwater biomes or shallow freshwater biomes
shallow
what is more diverse deep freshwater biomes or shallow freshwater biomes
shallow
what has more oxygen deep freshwater biomes or shallow freshwater biomes
deep
what has more photic zone deep freshwater biomes or shallow freshwater biomes
shallow
How many types of standing freshwater biomes are there
2
What are the two types of standing freshwater biomes
ponds and lakes
how many Moving freshwater biomes are there
2
what are the 2 moving freshwater biomes
streams and rivers
Moving Freshwater Biomes have a salt concentration _____ 1%
less than
Do rivers have alot of diversity why or why not
no bc they move fast
faster water = ______ diversity
less
Fresh Water Wetlands
soil that is always at least slightly submerged in water
Are streams diverse
no
Do fresh water wetlands have a lot of diversity/nutrients
yes
thermocline
the transition layer between the warmer mixed water at the surface and the cooler deep water below
lake
bodies of fresh water entirely surrounded by land
what are the different types of lakes
oligotrophic and eutrophic
Oligotrophic Lakes
clear, deep, cold lakes with a small amount of big fish –> lower productivity
Eutrophic Lakes
a lake with high nutrient levels, low clarity and very productive
littoral zone
the area where the water meets the land – like the sloping area
limnetic zone
part of lake that is penetrated by light
do intertidal zones have a lot of organisms
no bc its hard for organisms to have to survive in both air and water
what Is the biggest biome (amongst terrestrial and aquatic)
ocean pelagic zone
do ocean pelagic zones have a lot of organisms
ya
temp of Marine benthic zone
rly cold
marine biome
saltwater biomes
freshwater biome
biomes that have little to no salt
what are the freshwater biomes
ponds, lakes, streams, and rivers
what is bigger ponds or lakes
ponds
zones of lakes (also how many are there)
4: littoral, limnetic, profundal, benthic
profundal zone aka
deep water zone
profundal zone
part of lake with no light penetration so no photosynthesis
what has more oxygen in it the profundal or limnetic zone
limnetic
what organisms live in benthic zone
decomposers and organisms can withstand a low oxygen environment
what are streams and rivers important for
agents for erosion
source zone aka
headwates
source zone
where rivers/streams start –> high elevations where water collects because of precipitation and snowmelt
temp + speed of water in source zone
cold water + fast moving
what is the level of oxygen, nutrients, and species at the source zone
high oxygen and low nutrients and species
Transition zone
where the source zone waters merge so the river/stream is wider and there is more sediment carried along
what is the level of oxygen, nutrients, and species at the transition zone
less oxygen, more nutrients and species
temp + speed of water in transition zone
warm and slower (than source)
Floodplain zone
zone in the river where there’s a lot of sediment carried and the river kind of spills into wetlands or other small lakes
temp + speed of water in transition zone
warm + slower?
what is the level of oxygen, nutrients, and species at the transition zone
less oxygen, lots of nutrients and species variety
