25
Are Coral Reefs diverse
yes SUPERRRR
26
are Coral Reefs in shallow or deep water
shallow
27
Is a Coral Reef a Biome
yes
28
Where are coral reefs located?
in the photic zone of tropical waters above continental shelves
29
What is the base of a coral reef
cindarians that secrete a hard external skeleton and algae crusted with calcium carbonate
30
Wetlands
zones that are either submerged in water or completely submerged
31
How many types of wetlands are there
2
32
What are the 2 types of wetlands
Marine Wetlands and Freshwater wetlands
33
Estuary
where fresh water meets salt water
34
Are estuaries diverse
yes
35
Estuaries are a ______ for birds and fish
breeding ground
36
Freshwater biomes
standing fresh-water biomes
37
how many types of freshwater biomes are there
2
38
what are the two types of freshwater biomes
standing water and flowing water
39
what is more nutrient filled deep freshwater biomes or shallow freshwater biomes
shallow
40
what is more diverse deep freshwater biomes or shallow freshwater biomes
shallow
41
what has more oxygen deep freshwater biomes or shallow freshwater biomes
deep
42
what has more photic zone deep freshwater biomes or shallow freshwater biomes
shallow
43
How many types of standing freshwater biomes are there
2
44
What are the two types of standing freshwater biomes
ponds and lakes
45
how many Moving freshwater biomes are there
2
46
what are the 2 moving freshwater biomes
streams and rivers
47
Moving Freshwater Biomes have a salt concentration _____ 1%
less than
48
Do rivers have alot of diversity why or why not
no bc they move fast
49
faster water = ______ diversity
less
50
Fresh Water Wetlands
soil that is always at least slightly submerged in water
51
Are streams diverse
no
52
Do fresh water wetlands have a lot of diversity/nutrients
yes
53
thermocline
the transition layer between the warmer mixed water at the surface and the cooler deep water below
54
lake
bodies of fresh water entirely surrounded by land
55
what are the different types of lakes
oligotrophic and eutrophic
56
Oligotrophic Lakes
clear, deep, cold lakes with a small amount of big fish --> lower productivity
57
Eutrophic Lakes
a lake with high nutrient levels, low clarity and very productive
58
littoral zone
the area where the water meets the land -- like the sloping area
59
limnetic zone
part of lake that is penetrated by light
60
do intertidal zones have a lot of organisms
no bc its hard for organisms to have to survive in both air and water
61
what Is the biggest biome (amongst terrestrial and aquatic)
ocean pelagic zone
62
do ocean pelagic zones have a lot of organisms
ya
63
temp of Marine benthic zone
rly cold
64
marine biome
saltwater biomes
65
freshwater biome
biomes that have little to no salt
66
what are the freshwater biomes
ponds, lakes, streams, and rivers
67
what is bigger ponds or lakes
ponds
68
zones of lakes (also how many are there)
4: littoral, limnetic, profundal, benthic
69
profundal zone aka
deep water zone
70
profundal zone
part of lake with no light penetration so no photosynthesis
71
what has more oxygen in it the profundal or limnetic zone
limnetic
72
what organisms live in benthic zone
decomposers and organisms can withstand a low oxygen environment
73
what are streams and rivers important for
agents for erosion
74
source zone aka
headwates
75
source zone
where rivers/streams start --> high elevations where water collects because of precipitation and snowmelt
76
temp + speed of water in source zone
cold water + fast moving
77
what is the level of oxygen, nutrients, and species at the source zone
high oxygen and low nutrients and species
78
Transition zone
where the source zone waters merge so the river/stream is wider and there is more sediment carried along
79
what is the level of oxygen, nutrients, and species at the transition zone
less oxygen, more nutrients and species
80
temp + speed of water in transition zone
warm and slower (than source)
81
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
82
temp + speed of water in transition zone
warm + slower?
83
what is the level of oxygen, nutrients, and species at the transition zone
less oxygen, lots of nutrients and species variety
