400 Question Food Chains
Producers in one food chain obtain 300 energy
units from photosynthesis. How many energy units
will be transferred to the tertiary (3rd)
consumers?
9

300 x .1 x.1 x .1 .3
10
500 Question Food Chains
Consider a desert biome in which consumers rely
on producers as a water source. What would happen
to the producers in the biome if the population
of primary consumers suddenly decreased? What
would happen if the population of primary
consumers suddenly increased? Your answer should
consider the producers, and primary and secondary
consumers.
11
500 Answer Food Chains
If the primary consumer population decreased,
the producer population would likely increase,
though water availability would limit population
size as well.The secondary consumer populations
might decrease, because of lack of available
food.If the primary consumer population
increased, the producer population would
decrease, though the primary consumer population
is reliant on the producers as a water source.
Lastly, the secondary consumer population would
increase.

The inner membrane has a highly folded membrane
with a large surface area to provide more space
for chemical reactions.

400 Question Respiration
A sponge produces CO2 in a high oxygen
environment as a product of respiration. When
moved to a low oxygen environment, the sponge
stops producing CO2. What type of respiration did
the sponge undergo? How do you know?
39
400 Answer Respiration
The sponge was performing aerobic respiration. We
know because it produced CO2 as the product of
respiration in a high oxygen environment, but
ceased doing so in a low oxygen environment.
40
500 Question Respiration
Bacteria are prokaryotes, so they lack
membrane-bound organelles. Describe whether
bacteria can break down sugars to produce energy
and, if so, which processes they can use.
41
500 Answer Respiration
Bacteria can still perform simple glycolysis.
Glycolysis takes place in the cytoplasm. Some of
these bacteria can use the products of glycolysis
for lactic acid fermentation. Other bacteria
perform aerobic respiration in specialized
sections of their plasma membranes. Some bacteria
that did this took up residence in other cells
and became mitochondria..
42
100 Question Body Systems
By which process does O2 and CO2 get into and out
of the bloodstream? Is this the same as or
different from the process by which
digested nutrients get into the blood stream?
43
100 Answer Body Systems
Diffusion. Yes, it is the same process.
44
200 Question Body Systems
Name two ways food broken down as part of the
digestive system. Where and by what are lipids
digested?
45
200 Answer Body Systems
Food is digested mechanically (grinding with
teeth and churned in the stomach) and
chemically with enzymes. Fats are broken down
in the small intestines by bile and enzymes.
46
300 Question Body Systems
Explain how the respiratory and circulatory
systems are interrelated. Make sure to identify
any relevant parts!
47
300 Answer Body Systems
The respiratory system performs gas exchange with
the outside world, letting in O2 and out CO2.
Oxygen diffuses into the blood through air sacs
called alveoli that are wrapped in
capillaries. these capillaries are small blood
vessels. Blood travels back to the heart through
the pulmonary vein and then is circulated
through arteries, arterioles, capillaries,
venules and veins. The oxygen diffuses through
capillary walls into cells, and the CO2
diffuses from the cells into the capillaries.
48
400 Question Body Systems
Explain how the raw materials for respiration
(the reactants) get to a muscle cells
mitochondria through the circulatory, digestive
and respiratory systems. How does the waste
product leave the cell and get excreted
through the lungs?
49
400 Answer Body Systems
Oxygen is carried through the bloodstream and
diffused through the capillaries. Glucose (and
other digested foods) is diffused into the blood
stream from the small intestines villi and
microvilli. This travels to the muscle cell
through the blood. These are used in respiration
to produce ATP. CO2, the waste product, diffuses
out of the cells and is excreted through the
lungs.
50
500 Question Body Systems
Compare and contrast how gas exchange is done in
plants and humans. List at least three
similarities and three differences.

100 Question Photosynthesis
What are the yellow pigments found in leaves
called? What colors of light do they absorb? What
colors of light do they reflect?
53
100 Answer Photosynthesis
Yellow pigments are called xanthophylls. They
absorb all colors of light but yellow and
reflect yellow light.
54
200 Question Photosynthesis
Calculate the rf value of a pigment that travels
5 cm and a solvent that travels 25 cm. and for a
pigment that travels 10 cm and a solve that
travels 40 cm. Which pigment is larger? HOW DO
YOU KNOW?
55
200 Answer Photosynthesis
rf distance traveled by pigment/ distance
traveled by solvent Rf for first pigment
5cm/25cm .2 Rf for second pigment 10cm/40cm
.25 The first pigment is larger because its rf
value is smaller.
56
300 Question Photosynthesis
What is necessary for the light-dependent
reactions to take place? For each reactant,
state where it comes from. What is produced by
the light-independent reactions? What will that
product be used for in the plant/algae/etc.?
57
300 Answer Photosynthesis
Reactants NADPH and ATP - from the ETC of the
light-dependent reactions CO2 - from the
air Products 2 PGAL 1 Glucose That glucose
will be transported through the plant, via
phloem, to Places the plant needs energy. The
glucose is converted to ATP Through respiration.
58
400 Question Photosynthesis
The formula for fructose is C6H12O6, the same as
glucose. (Glucose and fructose are structurally
different but have the same chemical formula.)
Where does the carbon in fructose come from? How
did the carbon get into the plant? Your answer
should relate to photosynthesis!
59
400 Answer Photosynthesis
The carbon in fructose comes from the carbon
dioxide that the plant (or algae or bacteria)
takes in, possibly through stomata. CO2 diffuses
through the cells of the spongy mesophyll and
into the other cells of the leaf. That CO2 could
have come from respiration, including either the
plants own respiration or from other organisms,
or from other CO2 sources.
60
500 Question Photosynthesis
Design an experiment to test whether plants with
tightly packed cells in the palisades region of
their leaves are better at performing photosynthes
is than plants with more loosely packed
palisades regions. Your experiment should
include a concrete way to measure
photosynthesis! Predict which plant you think
will produce more glucose. WHY?
61
500 Answer Photosynthesis
Plants with tightly packed palisades layers have
more cells (and more chloroplasts) able to
perform photosynthesis because they will
have more surface area exposed to the sun,
therefore making it easier to harvest sunlight.
You could compare a plant with a loosely packed
palisades layer and a lightly packed layer by
selecting two plants, taking samples of each,
giving them CO2 and H2O, and measuring either
glucose or oxygen output. Oxygen output could be
measured in bubbles produced, leaf disks
floating, flame tests, or O2 sensors.
