Q

limnetic

A

light can reach

29
Q

profundal

A

to deep for photosynthesis

30
Q

benthic

A

bottom/ nutrient rich

31
Q

Estuaries

A

-Rivers in to the ocean
-Mixed of fresh and salt water
-high plant growth

32
Q

Coral Reef

A

-Warm shallow water
-Mutualistic relationship (algae (lives in coral) and coral)

33
Q

Open Ocean

A

-70% of Earth
-algae and phytoplankton can survive (asorbs CO2 and produce O2)

34
Q

Wetland

A

-soil submerged in water
-shallow or emergent plants
-plants are adapted to have roots soaked
- Benefits: stores excess water, roots filyter out pollutants, recharges ground water

35
Q

Salt Marshes

A

-temperate climates
-Breeding ground for plants
-Mangrove plants: tropical climates)
-Mangrove tress blacks the water

36
Q

Intertidal Zones

A

-Narrow band of coastline
-drying out
-organism adapt to waves

37
Q

Carbon Cycle

A

nature’s way of reusing carbon atoms, which travel from the atmosphere into organisms in the Earth and then back into the atmosphere over and over again (look in com book)

38
Q

Carbon sink

A

anything that absorbs more carbon from the atmosphere than it releases

39
Q

Nitrogen cycle

A

a biogeochemical process through which nitrogen is converted into many forms, consecutively passing from the atmosphere to the soil to organism and back into the atmosphere (look in comp book)

40
Q

Water Cycle

A

movement between sources and sinks

41
Q

Ocean is the…

A

largest water ressvoir

42
Q

Evaporation

A

vapor (stomata opens to allow water to evaporate)

43
Q

Precipitation

A

gas to liquid

44
Q

Amount of H2O that enters the atmosphere is from

A

Transpirsipitation and evaporation combined

45
Q

runoff

A

flows over earth’s surface into a body of water and gather pollutants

46
Q

Infilteration

A

trickes throughsoil down into ground water aquifiers

47
Q

important freshwater sources are…

A

ground and surface water

48
Q

Phosphurus cycle

A

Movement of P atoms and molecules between sources and sinks/ resevoirs

49
Q

Parts of a P cycle

A

-Slow
-no gas is in the cycle
-limiting nutrient
- all organisms need it
-Wind breaks down rocks and phosphate

50
Q

Major ressevoirs

A

Rocks and sediments

51
Q

Synthetic

A

sources of P like mining phosphate materials and adding it to products like detergent

52
Q

Assimilation

A

the process of incorporating a nutrient into an organism’s cells (similar to N cycle)

53
Q

Eutrophication

A

too much in N and P

54
Q

P sediments…

A

can be compressed over long periods of time

55
Q

algae bloom

A

covers surface of water

56
Q

Primary Productivity (PP)

A

rate of solar energy is converted into organic compunds

57
Q

High productivity

A
  • high plant growth
  • lots of food and shelter
    -More diverse species
58
Q

Respiration Loss (RL)

A

Planys use up some of the enrgy generated by photosynthesis

59
Q

Gross Primary Product (GPP)

A

total amount of energy plants catch and convert to energy through photosynthesis

60
Q

Net Primary Productivity (NPP)

A

Amount of energy leftover for plant growth (NPP= GPP-RL)

61
Q

Water availability

A

high temperature and nutrient Availability

62
Q

1st Law of Thermodynamics

A

energy is never changed or destroyed

63
Q

Due to Availability…

A

energy decreases with each step of the food chain

64
Q

troph

A

-Nourishment
-used to model energy moving through the ecosystem

65
Q

Producers

A

convert sunlight energy into chemical energy

66
Q

Food webs

A

Theflow of energy in a community

67
Q

Food chain

A

shows single pathways

68
Q

Trophic cascade

A

prey they eat increases but plants decrease and other animals that eat the plants also decrease (colapse of the food web)

69
Q

To caculate…

A

Move decimal point 8 (tertiary), 80Secondary consumer), 800 (primary consumer), 8000 (producer)
