Define biology - Correct Answer the study of living organisms and their interactions with each other and
their environments



Survivorship Curve Types - Correct Answer a graph of the number of individuals surviving at each age
interval plotted versus time



Batesian Mimicry - Correct Answer a harmless species mimmics/looks like a harmful species

i.e. hawk moth larva & green parrot snake



Mullerian Mimicry - Correct Answer two harmful species mimic each other

i.e. cuckoo bee & yellow jacket



cryptic coloration - Correct Answer species is camouflaged/more blended with its environment to hide
from predators

i.e. Indian leaf butterfly



aposematic coloration - Correct Answer species has bright, noticeable colors used to scare scare off
predators

i.e. poison arrow frogs, skunks



dominant species - Correct Answer - most competitive over resources

- most successful at avoiding predators

i.e. kangaroo, caribou



keystone species - Correct Answer - strong influence on community, influences other species

- NOT dominant or most abundant

, ecosystem engineers - Correct Answer - influence community by changing physical components of their
environment



primary succession - Correct Answer occurs in an area devoid of vegetation and usually has no topsoil

i.e. lava flow, retreating glacier



secondary succession - Correct Answer occurs in an area where a disturbance that affected pre-existing
populations begins to regrow

------topsoil still exists

i.e. forest fire



population - Correct Answer group of organisms of one species in one location that interact with each
other



species - Correct Answer group of individuals who interbreed and produce offspring capable of surviving
and able to reproduce themselves



ecosystem - Correct Answer - all the organisms living in a community

- biotic and abiotic interactions

- energy transformations



Two main processes in an ecosystem - Correct Answer 1) energy flow - always need constant supply of
energy

2) chemical cycling - always recycling the elements



At a minimum, what do you need in an ecosystem to recycle nutrients? - Correct Answer producers and
decomposers



first law of thermodynamics - Correct Answer energy cannot be created or destroyed, it is only
transformed
