19
Q

examples of aquatic biomes

A

freshwater bodies (lakes, rivers)
marine: ocean ecosystems

20
Q

how does temperature affect aquatic ecosystems

A

organisms have to go places where they can adapt to the temperature to survive

21
Q

how does dissolved oxygen affect aquatic ecosystems

A

if fish and other organisms aren’t getting enough oxygen in order to survive, they’ll die

21
Q

how does depth affect aquatic ecosystems

A

more pressure as you go down = less sunlight

22
Q

how does clarity affect aquatic ecosystems

A

sunlight can’t get though if there is algae covering the top layer of water

22
Q

how does light affect aquatic ecosystems

A

for photosynthesis

22
Q

how does dissolved nutrients affect aquatic ecosystems

A

the amount of nutrients can increase/decrease populations

23
Q

how does PH affect aquatic ecosystems

A

acid involved PH can cause death

24
Q

still vs flowing

A

river can flow and get rid of pollutants

25
Q

4 zones of lake in order from most to least productive

A
  1. Littoral
  2. Limnetic
  3. profundal
  4. benthic
26
Q

Littoral

A
  1. highest. productivity/biodiversity
  2. lots of sun = more plants
27
Q

Limnetic

A

1.lots of phytoplankton = highest oxygen

28
Q

Profundal

A

no photosynthesis
lowest oxygen levels

29
Q

Benthic

A

bottom of the lake

30
Q

what is/are the binomial nomenclatures

A

2 part name for species
genus and species

31
Q

genus

A

1st part: several species

32
Q

species

A

2nd: group of organisms that look alike
can interbreed to produce fertile offspring

33
Q

rules of binomial nomenclatures

A
  1. genus: First letter of first word is capitalized
  2. species: first letter of second word is not capitalized
  3. both words are italicized and underlined
34
Q

3 domain systems

A
  1. bacteria
  2. Eukarya
  3. Archaea
35
Q

bacteria

A

prokaryotic unicellular
lack of membrane nucleus
reproduce asexually
can exist in areas w/w out oxygen

36
Q

Eukarya

A

uni to multi cellular
bounded nucleus
some cell wall

37
Q

Archaea

A

prokaryotic unicellular
lack of membrane nucleus
can live in extreme environments

38
Q

dichotomous key

A

two part key used to identify living things

39
Q

protista

A

single/multi celled eukaryotic organisms

40
Q

Fungi

A

Single/multi called organisms
Create enzymes to digest food

41
Q

Plantae

A

Multi-celled eukaryotic organisms that use photosynthesis

42
Q

Animalia

A

multi celled Eukaryotic organisms that are heterotrophs
