500
This is an assemblage of parts & the
relationships between them, which together
constitute an entity or whole.
A 100
This movement normally involves a
flow through a system with a
change in location and an example.
A 200
This leads to an interaction within a system in
the formation of a new end product, or
involves a change of state with two
examples from the water cycle.
A 300
The types of systems shown & a realworld example of each.
A 400
This is the type of equilibrium in which there
is no change, AND the only natural system
that exists as an example.
A 500
The term for the return of part of the output
from a system as input, so as to affect
succeeding outputs.
B 100
A self-regulating method of control leading to
a steady-state equilibrium, it tends to damp
down, neutralize or counteract any deviation
& promotes stability.
Example: predator–prey relationships.
B 200
This leads to increasing change in a system, it
accelerates deviation & increases change
away from an equilibrium and an example.
B 300
Draw a feedback loop diagram
showing a predator/prey relationship.
B 400
The hypothesis that compared the Earth
to a living organism in which feedback
mechanisms maintain equilibrium
AND
The feedback mechanism involved
AND
whether or not this is supported by evidence.
B 500
This is the study of energy transfers &
transformations.
C 100
This law states that energy can neither be
created nor destroyed. (conserved)
C 200
The 2nd law of thermodynamics states that
this amount of energy will flow
and
this amount will be lost
in a food chain/web.
C 300
DAILY
Place A Wager
DOUBLE
C 400
This is a measure of the amount of disorder,
chaos or randomness in a system
AND
The Law of Thermodynamics that it
illustrates.
C 400
Show your calculations
C 500
These determine the nature and structure
of an entire ecosystem. Usually found in
small numbers but have a key influence.
• Examples: Wolves
D 100

D 200
Ecological principle illustrated here.
D 300
The three requirements for all stable
ecosystems…
D 400
This is the gain by producers in
energy/biomass per unit area per time that is
potentially available to consumers
AND
the equation used to calculate it.
D 500
This formula is used to estimate the
population of a species in a given area
at a given time.
E 100
The technique used to tag animals of interest
and the formula used to calculate estimated
population.
E 200
• Calculate the Lincoln’s index using the
following data:
• Fiddler crabs captured/marked = 210
• 5 days later = 289 caught with 68
marked.
• Estimated total population = ?
E 300

Index
E 500
The identity of X & Y in this pyramid of
biomass.
F 100
The types of pyramid shown
AND
the reason why this pyramid
has a different pattern
F 200
This is why this pyramid has a different
pattern. (processes)
F 300
The 3 types of pyramids used as graphical
models in ecosystems
AND
The quantitative units used for each.
F 400
Label the missing biomass values x,y,z
AND The type of consumers AND
The trophic levels A, B, C, D.

Feedback & Predator/Prey Relationships
Identify the difference shown & explain why
it exists.
Feedback & Predator/Prey Relationships
The difference = Lag time, Why it exists = prey 1st
predators respond later (eat the prey)

B 400
The Gaia hypothesis compared the Earth to a
living organism in which feedback
mechanisms maintain equilibrium
AND
The feedback mechanism involved = negative
Presently NOT supported by evidence since
Earth keeps getting hotter.

D 300
Stable ecosystems have…

energy into organic compounds (food).

and the environment.

AND
Reason = during the summer large trees can
