At what point does this curve
demonstrate exponential growth?

Define ‘Carrying Capacity’
Give an example of
a population
(other than humans)
List four limiting
factors.
List two densitydependent, biotic
factors influencing
population growth.
Define ‘Community’
Define ‘Habitat’
Define ‘Ecosystem’
What is the process diagram below
called (be specific)?
Explain what is
meant by ‘energy
flows’ and ‘nutrients
cycle.’
On the board, diagram
the water cycle.
On the board, diagram
the carbon cycle
(include four
forms/influences).
Where is most nitrogen
on planet Earth found?
Explain three forms of
nitrogen found on
Earth.
What Type of Plants
help with
Nitrification?
HIV-AIDS is a virus that uses human
cells to reproduce itself, destroying
the human cells in the process. What
type of interaction is demonstrated in
this example?
Squirrels will feed on
the eggs of birds. What
type of interaction is
this?
Some ducks fly from wetland to
wetland, sometimes carrying
seeds on their feet. The process
helps the plants inhabit new
wetlands. What type of species
interaction is this?
In your gut, you have E. coli bacteria
that help you digest your food. In
return, they get a safe place to live,
warmth, and supply of food. What
type of interaction is this?
Give an example of commensalism.
Circle the Producers:
Circle Two Consumers:
Circle An Organism from the 3rd
Trophic Level:
If you start with 100,000
calories of energy at the level
of producers, how much
energy will be available for a
tertiary consumer?
The rule of 10% states
that most energy isn’t
transferred from one
trophic level to the next.
Where does the ‘lost’
energy go?
