1. Look at the diagram below:
Based on your knowledge of how the sun’s energy flows through food chains and food webs, which
living things belong in the spaces labeled “X”, “Y”, and “Z”?
2. Compounds are formed from the combination of two or more elements. Some compounds are
inorganic, while other compounds are organic. Which of the following compounds is an organic
compound?
a. Sodium chloride (NaCl)
b. Methane (CH4)
c. Water (H2O)
d. Hydrogen chloride (HCl)
3. The digestion process begins when you begin to chew food. Chewing food cuts and grinds food
into smaller pieces so that it is more easily swallowed. During chewing, your mouth releases saliva
which contains enzymes to turn the food into a form that can be used by cells. What type of change
takes place in your mouth when you chew?
a. Physical change during the entire process of digestion in the mouth
b. Chemical change during the entire process of digestion in the mouth
c. Physical change when food is cut and ground and chemical change when food is mixed
with saliva
d. Chemical change when food is cut and ground and physical change when food is mixed
with saliva.
4. Four girls push wheelbarrows filled with dirt up four different ramps.
The work performed on an object is determined by the force applied to the object multiplied by the
distance the object moves as a result of the force. All four girls do the same amount of work on
their wheelbarrows. Which girl must exert the greatest amount of force on her wheelbarrow to
move it up her ramp?
a. Girl A
c. Girl C
b. Girl B
d. Girl D
5. Biodiversity is the degree of variation of life forms within a given ecosystem, biome, or an entire
planet. Biodiversity is a measure of the health of ecosystems. Greater biodiversity implies greater
health. Which of the following scenarios does NOT correctly describe how the biodiversity of an
ecosystem contributes to the sustainability of that ecosystem?
a. Plants and animals in the ocean thrive when a greater variety of species lives within a habitat.
b. Terrestrial animals are able to live and reproduce when a significant variety of plant life is
available within an ecosystem
c. Plants and animals in an arctic tundra have little biodiversity, therefore low sustainability.
d. An ecosystem consisting of all abiotic components will have a greater change of sustainability.
6. Students in Mrs. Whitman’s science class learn that groundwater is an important source of drinking
water for many communities. They construct a model to study how leaking chemicals from a
landfill can affect groundwater.
7. Study the drawing showing the progression of ecological succession following a forest fire.
What is the role of the pioneer species that appear first in the ecological succession of the
burned forest?
a. The pioneer species colonize and modify the forest floor, allowing other species to invade the
area.
b. The pioneer species prevent new fires from starting in the forest.
c. The pioneer species prevent other species of plants from invading the area.
d. The pioneer species mutate into new species that are resistant to forest fires.
8. A tornado is a funnel shaped wind storm caused by temperature differences in unstable air masses.
What kind of effect would a tornado have on the different ecosystems?
a.
b.
c.
d.
Ground becomes very dry and hard and will begin to crack
Fast moving water picks up debris, rocks and sediment
Can pull up large trees, blow away small vegetation and move soil
Hot lava and ash destroy vegetation
9. The image above is illustrating Photosynthesis. What type of energy transformation is taking
place?
e.
f.
g.
h.
Chemical Energy to Mechanical Energy
Thermal Energy to Radiant Energy
Radiant Energy to Chemical Energy
Kinetic Energy to Potential Energy
10.The picture shows a Turgor Pressure demonstration using celery. Place the picture of the celery in
order of least amount of pressure to the greatest amount of pressure.
a. Q,R,S,T
b. S,R,Q,T
c. Q,R,T,S
d. S,T,Q,R
11.All of the following are examples of how energy stored in food is transformed into other forms of
energy during digestion except –
a. The chemical energy stored in food is transformed into thermal energy used to maintain
body temperature.
b. The chemical energy stored in food is transformed into mechanical energy used for
movement.
c. The chemical energy stored in food is transformed into chemical energy stored in fat.
d. The chemical energy stored in food is transformed into radiant energy use for
photosynthesis.
12.Which of the following statements best describes the breakdown of large food molecules into
smaller molecules?
a. Enzymes mechanically breakdown large food molecules into smaller molecules
b. Large molecules are broken down into smaller molecules that contain new elements
c. The breakdown of food molecules begins in the small intestines
d. Enzymes aid the chemical breakdown of large food molecules into smaller molecules
13.Which of the following statements about digestion is true?
a. Digestion is needed to break down proteins and complex carbohydrates into molecules
that are small enough to get to cell of the body.
b. Digestion is only needed to break down proteins into molecules that are small enough to
get to cells of the body. Complex carbohydrates are already small enough to get to cells
of the body.
c. Digestion is only needed to break down complex carbohydrates into molecules that are
small enough to get cells of the body. Proteins are already small enough to get to cells of
the body.
d. Digestion is not needed to break down either proteins or complex carbohydrates because
these molecules are already small enough to get to the cells.
14.In a healthy forest, dead trees and limbs fall to the ground and decompose. Which of these
statements best describes why decomposition is important to a forest ecosystem?
a. Nutrients are released and returned to the soil when wood is broken down.
b. Worms produce oxygen used by other organisms.
c. Dead trees provide nest sites for many different species of birds.
d. Water is stored in dead trees and limbs.
15.Examine the graph provided. Two populations of chimpanzees live in two different areas of a
jungle region. The jungle area where Population B is located has higher biodiversity than the
jungle area where Population A is located.
a.
Chimpanzees in Population A
have a lower survival rate because the
biodiversity is less.
b.
Chimpanzee survival is not
dependent on tree diversity in any part of the
jungle
c.
Chimpanzees in Population B
have a higher survival rate because the
biodiversity is high.
d.
Both A and C
16.A student is growing a plant in a pot and keeps it sitting on a table near her bedroom window. She
