What is bioaccumulation?
List 3 types of Natural Disturbances that
could be limiting factors for population of
species.
A series of interconnected food chains. Food
chains represent the flow of energy from
producers through to varying levels of
consumers.
The buildup of pollutants in organisms. As
pollutants move through the food chain,
pollutants remain in the organism’s tissues.
What is a producer (in a food chain)?
What is the definition of Limiting Factors?
An organism that is able to make its own
food through the process of photosynthesis.
Any abiotic (non-living) or biotic (living)
factor that controls the number of
individuals in a population.
Carbon-containing materials are passed
along from organism to organism through
the food chain. When organisms use food
for energy, the carbon is converted back into
carbon dioxide and is available for plants to
use again.
What is the cyclical order of the Water
Cycle?
Explain why top consumers have the most
pollutants in them.
What is a Primary Consumer?
-Avalanche
-Tsunami
-Landslide
-Earthquake
-Fire/Lightning
-Drought
-Flood
-Extreme Weather
Explain the Carbon Cycle.
An animal that eats a producer.
Evaporation ---> Transpiration --->
Condensation ---> Precipitation ---> Ground
Water/Run Off
As pollutants enter the food chain, they are
stored in the tissues of organisms. As other
animals consume these polluted animals, the
pollutant is passed on and becomes more
concentrated. Top consumers end up
getting the most pollutants.
What is a Secondary Consumer?
An animal that eats a primary consumer (can
also eat producers)
What is Transpiration?
What is a Tertiary Consumer?
A forest fire would drastically change an ecosystem.
Over time, since there is no forest canopy, rain and
sunlight can reach the ground. Small grasses, plants
and shrubs will start to grow. Consequently, small
insects and rodents would move back into the
ecosystem. As more vegetation grew, and primary
consumers increased, secondary consumers would
start to move back. As more species start to inhabit
the ecosystem, it is revived again. This is a very SLOW
process and involves gradual change.
When water is absorbed through plants’
roots and evaporates through the leaves,
stem and flowers.
An animal that eats a secondary consumer
(can also eat primary consumers and
producers)
What is a Quaternary Consumer?
An animal that eats a tertiary consumer (can
also eat secondary/primary consumers and
producers)
Evaporated water in the form of gas collects
and cools in clouds. The cooled gas is
condensed and turns back into water in the
form of precipitation.
What is Evaporation?
How many
food chains
are in this
food web?
There are 18 food chains
What is Carrying Capacity?
The measure of the variety of species in an
ecosystem.
The maximum number of individual
organisms that an ecosystem can support.
What is precipitation? What are its forms?
What is the definition of pollution?
When water falls from clouds back to the
surface of the Earth in the form of rain, hail,
sleet or snow.
Any substance that is added to an
environment that cannot be broken down,
stored or converted into a form that is not
harmful. Pollutants cause pollution.

so? Where does it go?
-Temperature
-Predation
When organisms die, they become part of the thick
-Predator/prey cycles
carbon containing material at the bottom of

people use this fuel, or burn coal/oil, the energy is
released and carbon is converted into carbon dioxide.
Using the example of a forest fire, explain
what Ecological Succession is.
What is Condensation?
What is biodiversity?
When water lakes, oceans, rivers, etc. is
heated from the sun and turned into water
vapor.
When water falls back to Earth in the water
cycle, what are the two things that could
happen to it after it hits the ground?
If a top consumer was removed from a food
chain, explain the effects it would have on
that food chain.
It will either soak into the ground (ground
water) or be stored in the water table, or it
will run off the land into lakes, ponds, rivers,
streams and oceans.
It would have negative effects on the food chain. Top
consumers are predators and keep populations of
species under control. If species are no longer prey
for predators, there population will increase. This in
turn, will put stresses on the amount of food available
for the growing population. This will lead to
competition for resources and could eventually wipe
out the producers.
Why is it important for farmers to have a
buffer of trees and vegetation between
their fields and a water source?
The buffer of trees and vegetation will help
to absorb any pollutants that might be on
the farmer’s field (pesticides or animal feces)
and limit the chances of it getting into the
water (which could affect that ecosystem)
In a food chain diagram, what do the arrows
the arrows represent?
Hint: What is flowing up through the food
chain?
The arrows represent the flow of energy.
