This is the source of all energy in
an ecosystem
The sun
This is the name given to all the
living parts of the environment
Biotic Factors
Water, temperature, and air are
this type of factors
Abiotic
This is the name given to
organisms that make their own
food, from solar energy
Producers/autotrophs
What is another name for a
consumer?
Heterotroph
This is the type of relationship
between a flea and a dog
Parasitism
Bacteria in the stomachs of cows
help cows digest their food. We
describe this as this type of
relationship…
Mutualism
This word is used to describe
how organisms interact with one
another we define it as “living
together”
Symbiosis
An orchid can use a tree trunk to
receive extra nutrients, it does not
hurt the tree by growing on
it…this is an example of:
Commensalism
A lion may hunt a zebra. They
belong to different trophic levels.
Name what type of consumer the
lion and zebra would be?
Lion= secondary consumer
Zebra= Primary consumer
What do the arrows represent in a
food chain
Grass
Rabbit
Fox
Energy transfer
This is the name given to
organisms that eat both animal
and plant material
Omnivores
(Tertiary Consumers)
Animals that eat plants only are
called
Herbivores
(Primary consumers)
Organisms that include bacteria
and fungi are called:
Decomposers
How many herbivores are in the food web
above?
Three: Grasshopper, squirrel and
rabbit
This is what we call anything that
takes up space
Matter
Give an example of types of
matter that get recycled in the
environment
Water, Carbon
At
In an energy pyramid, organisms at
the top only get a certain amount of
energy, because most energy is lost as
heat and waste material. What do we
call this rule?
10 % Rule
What happens to all the matter that exists
on earth?
It gets recycled
What process shown above, decreases
the amount of carbon dioxide in the
air?
Photosynthesis
As a predator population increases,
what happens to the prey population?
Decreases
What do we call this type of
growth?
Exponential (J-curve)
What is another name for
carrying capacity ?
(K)
Space, births, mates, food are
considered this type of factors….
Density-Dependent
What does the dashed line
represent?
Carrying capacity (K)
