10%
41
What are food webs
food chains linked
42
Is a food web more realistic than a food chain
Yes
43
pyramid of numbers
shows the number of organisms on each level
44
Pyramid of biomass
how much each level weighs
45
Bioaccumulation
substance builds up in an organism’s body from the surrounding air or water, or through consumption
46
Bioaccumulation
substance builds up in an organism’s body from the surrounding air or water, or through consumption
47
Biomass
total mass of all the organisms in an ecosystem.
48
What does changes in either abiotic and biotic factors do
affect the members of the food web
49
Bioaccumulation
substance builds up in an organism’s body from the surrounding air or water, or through consumption
50
Run-off
Water that runs off the ground into lakes, rivers or streams.
51
Run-off
Water that runs off the ground into lakes, rivers or streams.
52
Ground water
Water stored in soil
53
what do we call when matter continually moves from the abiotic environment to the biotic environment.
a cycle
54
Ground water
Water stored in soil
55
what are living and non living things made of
made up of matter.
56
4 major components of the water cycle
* Evaporation * Transpiration * Condensation * Precipitation
57
Ground water
Water stored in soil
58
Run-off

62
Ecology
study of organisms and how they interact with the environment around them
63
Ecologists
people study the interactions between living things and their environment
64
Quadrat Analysis
square plot that represents the surrounding ecosystem – create an population estimate
65
Bioinvasion
New species added to the food web/chain
66
When is a species considered invasive
when its ability to survive in its new conditions allows it to outcompete species.
67
Predator
organisms that catches and eats other organisms
68
Prey
organisms that is caught and eaten
69
Does the relationship between predator and prey cause both organisms to evolve
Yes

Weather
71
Succession
