Transcript The percentage of energy that is passed onto the next trophic level.

Ecology Review Jeopardy
The percentage of energy that
is passed onto the next
trophic level.
What is 10%.
CO2 + H2O  C6H12O6 + O2
What is the equation for
photosynthesis.
Eats both plants and animals.
What is an omnivore.
Shows the direction that
energy flows, from producers
to top carnivores, in a
simplified single path.
What is a food chain.
Makes their own energy/food
source (e.g. a plant).
What is an autotroph.
Waste or decaying matter
from plants or animals.
What is detritus.
Explain the difference
between the following terms:
population, community.
Population is a group of the
same species. Community is a
group of different
populations.
Why do oligotrophic lakes
eventually become eutrophic
lakes?
Sediment builds up over time
from erosion and human
activity, making it shallower.
This type of lake has more
communities (more
biodiversity). Explain why.
Eutrophic. There are more
nutrients (although less
oxygen).
The accumulation of toxins up
the food chain.
What is bioaccumulation /
bioamplification.
The water quality test that
indicates the presence of
decomposing microorganisms
in the water (e.g., bacteria).
What is the B.O.D. (Biological
Oxygen Demand).
The source of pollution of a
murky, stinky river.
What is non-point source
pollution.
Word AND chemical equation
of cellular respiration.
oxygen + sugar (glucose)  carbon dioxide + water
O2 + C6H12O6  CO2 + H2O
The temperature when water
becomes less dense.
What is 4˚C.
Nonliving factor that can
affect an ecosystem. Give an
example.
What is abiotic factor.
(e.g., temperature, water, pH…)
What are the four factors that
determine a species’ biotic
potential?
1.
2.
3.
4.
Length of the reproductive life.
Birth potential.
Procreation.
Capacity of survival.
The form of nitrogen that
plants need…and how they
get it.
What is NITRATE, and
bacteria/lightning.
Describe how too much
nutrients eventually lead to
death in an aquatic ecoystem.
• Aquatic plants thrive – algal bloom.
• Build up of detritus from plants.
• More decomposition, therefore more
bacteria.
• Decomposers (bacteria) use up O2
(high B.O.D.).
• Amount of dissolved O2 drops – death
to aquatic life.
Options when a consumer’s
prey population drops.
• Start preying on something else.
• Migrate.
• Lower own population (die or
breed less).
Name two problems with
pesticides.
Fat-soluble – stays in tissues
and leads to bioamplification;
pests build up resistance.
Layer between the epilimnion
and the hypolimnion.
What is the thermocline.
Occurs during spring/fall
turnover in lakes.
Cold surface water (more dense)
drops, carrying dissolved oxygen,
nutrients from lower levels of
water get recycled.
How water gets from plants
to the atmosphere in the
water cycle.
What is transpiration.
The view that we should not
interfere (for good or bad)
with nature.
What is ownership view.
The view that nature has stuff
that we need and should use.
What is frontier view.
The view that we should
protect and actively save
nature.
What is stewardship view.
A nutrient with small
availability affects population
growth.
What is a Limiting Factor.
