9
Q

taxonomy

A

science to describe and name species

10
Q

carbon cycle

A

carbon circulates through living and non-living systems, occurs in the ecosphere CLOSED

11
Q

nitrogen cycle

A

three basic stages: nitrogen
fixation, nitrification and denitrification

12
Q

positive feedback loops

A

increases changes and drives the system toward a tipping point where a new equilibrium is adopted (global warming)

13
Q

negative feedback loops

A

a normal biological repsonse in which the affects of a reaction will return to its original state

14
Q

biodiversity

A

includes diversity of species, genetic, habitat.

contributes to security and resilience

15
Q

primary pollutants

A

active on emission - carbon monoxide from fossil fuels

16
Q

secondary pollutants

A

primary pollutants undergoing physical or chemical changes

17
Q

kyoto protocool

A

agreement to reduce carbon emissions

18
Q

open system

A

system that allows the exchange of matter and energy
eg. a plant

19
Q

closed system

A

system that does not exchange matter but it does exchange energy

eg. earth

20
Q

isolated system

A

does not exchange energy nor matter

21
Q

entropy

A

the amount of disorder in a system

22
Q

food chains

A

interconnectedness between species (predators, decomposers)

23
Q

2nd law of thermodynamics

A

energy is transformed = loss of energy through the release of heat

entropy increases over time

24
Q

parasitism

A

relationship between two species in which one species
(the parasite) lives in or on another (the host), gaining its food from it

25
Q

mutualism

A

relation between two or more species in which all benefit and none suffer

26
Q

commensalism

A

when one partner is helped and the other is not significantly harmed

eg. a fern growing up a tree trunk

27
Q

biotic factors

A

the living components of an ecosystem

28
Q

abiotic factors

A

the non- living components of an ecosystem

eg. light availability

29
Q

gross primary productivity (GPP)

A

the total gain in
energy or biomass per unit
area per unit time by green
plants

30
Q

net primary productivity (NPP)

A

the total gain in
energy or biomass per unit
area per unit time by green
plants after allowing for
losses to respiration.

31
Q

gross secondary productivity (GSP)

A

the total energy or biomass assimilated by consumers

GSP = fecal loss mass - food consumed

32
Q

net secondary production (NSP)

A

only the food that crosses the digestive system wall of animals is absored

33
Q

natural selection

A

the process through which populations of living organisms adapt and change

34
Q

Demographic transition model

A

a diagram that shows how the population of a country changes over time

35
Q

Impacts of an invasive species

A
  • introduction of disease
  • habitat alterations
  • displacement of species
36
Q

niche

A

set of biotic and abiotic conditions and resources to which an organism or population responds
