|
Biological Magnification
|
-DDT is sprayed to kill insects
-DDT is not biodegradable; stays in ground and in living tissue and can be passed on easily |
|
|
Carrying capacity
|
the largest # of organisms that can be supported in a given area under given conditions
|
|
|
Biomes
|
A combination of many ecosystems which share the same climate and vegetation
|
|
|
Benthic vs. Nekton vs. Planktonic
|
B= Lowest part of a body of water (Bottom dwellers)
N= Middle part of a body of water (swimmers) P= highest part of a body of water-small part (free floaters) |
|
|
Biotic affecting Abiotic (Vice Versa)
|
The sun (abiotic) gives the plants (biotic) energy to survive.
|
|
|
Red Tide (Cause, organisms affected, etc.)
|
-Cause: excess growth of algae, called an algal bloom, in warm water from pyrrophyta
-produce neurotoxin (nerve poison) -organisms effected: clams, mussels, scallops (because of filter feeding) |
|
|
Causes of Species extinction
|
Food & space
|
|
|
pH Scale (acid vs. basic) 1=?, 7=?, 14 =?
|
1 = acidic, 7 = neutral, 14 = basic
|
|
|
Predator-prey relationships
|
Predator goes up, prey goes down (vice Versa)
|
|
|
Biological Control
|
Using another species or population to control the growth rate of a particular population
|
|
|
Mammals that can hibernate
|
-Jumping Mouse
-Little brown bat -Woodchuck |
|
|
Physiological, behavior, Morphological adaptations
|
P = how the body works internally (ex: deer metabolism - change what can eat in winter)
B = an action (ex: migration) M = outward body structure (ex: color change = chameleon) |
|
|
List of Abiotic factors
|
-gases
-light -H20 -pH -currents |
|
|
List of Biotic factors
|
-animals
-plants -decomposition |
|
|
Quadrant, Transect, Random Sampling, Capture/Mark/Realease
|
Q = 4 sided study area
T = A line of study crossing a variety of areas RS = ex: marked 10 geese and then released them back into the population. Over a 6 year period, geese were trapped and their numbers recorded. C/M/R = plot a 10x10 area and randomly chooses 5 spots, where you count the # of objects in the plots and record them on a grid. |
|
|
Producer (Autotroph)
|
makes its own food
|
|
|
Heterotrophs
|
take in food
|
|
|
Herbivore
|
eats producers
|
|
|
Carnivore
|
eats meat
|
|
|
Omnivore
|
all eater (humans)
|
|
|
Parasite
|
feeds off living things
|
|
|
Decomposer
|
recycle dead organisms into original nutrients (earthworms)
|
|
|
Interrelationships (Predation)
|
Ex: wolves and deer
|
|
|
Interrelationships (mutualism - where both benefit)
|
ex: rhino and tickbird
|
|
|
Interrelationships (Commensalism- one benefits, one unaffected
|
ex: shark & Remora
|
|
|
Interrelationships (Parasitism - one benefits, one harmed)
|
ex: mosquito
|
|
|
Denitrification
|
N03 (nitrate) becomes N2 (gas) and goes into atmosphere
|
|
|
Nitrogenfixation
|
N02 (nitrite) becomes N03(nitrate) and can be taken in by plants
|
|
|
Ammonification
|
waste/urine and dead organic matter converted from NH3(ammonia) into NH4(also converts N2 to NH4)
|
|
|
Legumes
|
plant organisms involved in getting nitrogen gas into N03
|
|
|
Nitrogen fixing bacteria
|
organisms in a mutual relationship with the plants above in getting nitrogen into a usable form
|
|
|
Bacteria
|
kind of organisms in the soil involved in every step of the nitrogen cycle, named after their particular task
|
|
|
Eating
|
major niche of the above organisms
|
|
|
assimilation
|
how the animals get nitrogen
|
|
|
Desert
|
C = very little rain/ hot days, cold nights
S = dry & poor V = cacti |
|
|
Tundra
|
C = little rain/ short, cool summer & long, cold winter
S = shallow permafrost V = lichen |
|
|
Grasslands
|
C = violent rainstorms or a drought/ dry, hot summer & cold winters
S = rich & deep V = grasses/ few trees |
|
|
Tropical Rainforest
|
C = lots of rain/ hot & humid
S = shallow and poor because most nutrients are in trees V = vines, large leaf plants |
|
|
Taiga (Boreal) (Coniferous Forest)
|
C = lots of snow and rain/ short, cool summer & long cold winter
S = acidic V = pine/ conifers |
|
|
Temperate Deciduous forest
|
C = moderate/ warm summer, cold winter
S = good, deep soil V = deciduous (oak,maple,poplar) |
|
|
Results in burning the Rainforest
|
-C02 is released in the air
-many nutrients are in the trees (plants & animals die/ use for medicines) |

|
|
Density independent factors
|
factor which effect a population the same regardless of population size
|
|
