abiotic

nonliving
biotic
living/once alive
species
group of similar organisms that can freely interbreed.
population
members of the same species living in the same area at the same time.
lithosphere
what is one kcal?
Amount of energy needed to raise the temperature of 1 kg of water 1°C
potential energy
o  
what is the first law of thermodynamics?
o   Energy cannot be created or destroyed.

o   Amount of energy present in the universe at its formation is the amount that exists today.

whats the second law of thermodynamics?
o   When energy is converted from one form to another, some is degraded into a less usable form (heat) that goes into the surrounding environment.o  
entropy
Measure of disorder
chlorophyll
Green, absorbs radiant energy  
trophic levels
the feeding levels in a food chain or food web.  
producers are known by what other name?
autotrophs
detritus
organic matter that includes animal carcasses, leaf litter and feces
how do hydrothermal vent communities derive energy?
whats a food web and whats so great about it
a complex of interconnected food chains in an ecosystem. A food web is a much more realistic model of the flow of energy through an ecosystem because it shows multiple possibilities, whereas the food chain shows only one
energy flow is always _______.
linear (one way)
pyramid of numbers
pyramid of biomass
This pyramid indicates the total mass of the organisms in each trophic level
pyramid of energy
The Energy pyramid indicates the total amount of energy present in each trophic level
net primary productivity =
NPP = GPP – CELLULAR RESPIRATION
ecosystem
 a biological community and its abiotic environment 
keystone species
an organism that is vital in determining the nature and structure of an entire ecosystem
coevolution
the change of a biological object triggered by the change of a related object
symbiosis
any intimate relationship between members of two or more species.

 

mutualism
a symbiotic relationship in which both partners benefit
commensalism
a type of symbiosis in which one organism benefits and the other one is neither harmed nor helped
parasitism
give 2 animal defenses
many animals can run very quickly, burrow, have spines or quills, shells, some live in herds, skin toxins, warning coloration, camouflage or sharp teeth and claws.
give 2 plant defenses
plants have spines, thorns, tough leaves, thick wax or toxins (nicotine).
fundamental niche
realized niche
·      The niche that an organism actually fulfills.

It is more limited due to competition

limiting factor
Characteristics of an ecosystem which determine if an organism can live there
competitive exclusion
o  
ecotone
transitional zone between ecosystems
natural selection
The species which are naturally best adapted to their environment survive to reproduce
primary succession
Succession where there is no soil.
pioneer community
secondary succession
·      Succession where the ecosystem has been destroyed but there still is soil.
