What are the two components of species diversity?
(Define, too!)
10 Community 1

(1) Species richness- amount of species
present(2) Species abundance- the amount of
organisms that make up each species, aka
evenness

Define Keystone Species.
20 Community 1

A species that exerts strong control over a
community because of its niche

environment until some disturbance occurs.

this lead to and why?

fire)Increased species diversity overtime.

Define Coevolution.Which community interaction
demonstrates this?
40
Community 2
20
Herbivory- Coevolution occurs when a change in
one species acts as a new selective force on
another species, and counteradaptation of the
second species in turn affects the selection of
individuals in the first species.

21
Define the competitive exclusion principle.
50
Community 2
22
50
Community 2
two species so similar that they compete the same
limited resources cannot coexist in the same
place.

Ecosystems 1- Energy Flow
Define Ecosystem.
24
consists of all the organisms in a community as
well as the abiotic environment with which the
organisms interact.
10
Ecosystems 1- Energy Flow
25
Define Energy Flow.
20
Ecosystems 1- Energy Flow
26
the passage of energy through the components of
the ecosystem..
20
Ecosystems 1- Energy Flow
27
Why isnt all of the energy transferred from one
trophic level to the next? Where does it go?
30
Ecosystems 1- Energy Flow
28
30
Ecosystems 1- Energy Flow
Energy is lost as heat through cellular
respiration and through wastes.
29
Explain what is represented through a Pyramid of
Production (including units)
40
Ecosystems 1- Energy Flow
30
40
Ecosystems 1- Energy Flow
Illustrates the cumulative loss of energy with
each transfer in a food chain. Only about 10 of
energy is actually passed on to each trophic
level. measured in joules or calories
31
What is primary production?Which ecosystem
provides the greatest primary production for the
biosphere?
50
Ecosystems 1- Energy Flow
32
is the amount of solar energy converted to
chemical energy (organic compounds) by an
ecosystems producers for a given area and during
a give time period.Open ocean

Ecosystems 2- Chemical Cycling
What happens to chemicals in an ecosystem that
differs from what happens to energy?
34
10
Ecosystems 2- Chemical Cycling
Chemicals are recycled
35
20
Ecosystems 2- Chemical Cycling
How do animals get Carbon?
36
20
Ecosystems 2- Chemical Cycling
By consuming plants and/or animals that have
consumed plants.

What are the abiotic reservoirs for nitrogen?
38

Ecosystems 2- Chemical Cycling
Atmosphere and soil

Ecosystems 2- Chemical Cycling
How does Carbon get back into the abiotic
reservoirs?

Ecosystems 2- Chemical Cycling
How do plants get nitrogen? (explain at least two
ways)
42
50
Ecosystems 2- Chemical Cycling
PLANTS NEED NITROGEN IN THE FORM OF NO3-
(NITRATE!!) lightning turns N2 to
NO3- Nitrogen-fixing bacteria turn N2 to NH3 and
nitrifying bacteria turn NH3 into
NO3- decomposers produce NH3 when they consume
dead organisms, which will be turned into NO3- by
nitrifying bacteria wastes contain NH3, which
will be turned into NO3- by nitrifying bacteria.

What is resource partitioning and what causes it?
52
30
Potpourri
It is a way in which different species can use
the same resource, such as food, without
occupying the same physical location at the same
point in time. Caused by interspecific
competition.
