
1. Draw and label a
diagram of the water
cycle. Be sure to have
the following label:
Evaporation,
condensation,
precipitation,
runoff,
transpiration, and
accumulation
Water cycle
2. What happens during
condensation? Does
Earth only experience
condensation in the
clouds? Why or why
not?
Condensation happens
when water vapor turns
to liquid water in the
clouds.
Condensation can only
happen in the clouds
because when the water
vapor turns from liquid
water the cloud gets
heavy so than it starts to
rain, sleet, hail, or snow.
3.If we had too many
plants, then we would
have too much oxygen
in the air
if we had too may
animals or pollution,
then we would have
too much carbondioxide in the air.
4. Describe the difference
in inherited traits vs.
learned behavior. Give 5+
examples of each
Inherited traits are traits that are
passed down from your parents.
1) Color of eyes
2) Color of skin
3) Color of hair
4) Size
5) If an animal has spots
Learned behavior are taught to
you
1) To jump
2) To walk
3) To write
4) To drive
5) To cook
5.Define the following &
give at least 2
examples of each.
Producer: an organism that makes its
own food.
ex: plant and animals
Consumer: an organism that cant
make their own food and so eat plant
or animals.
ex: people, foxes, and rabbits
Decomposer: dead plant or animal
that gives off nutrients
ex: plants and fungi
Herbivore: plant eater
ex: rabbits and white tailed deer
Omnivores: eats both plants and
animals
ex:
humans and black bear
Scavengers: animals that eat of all
ready dead animals
ex: vulture and Hyenas
Niche: a role a organism plays in its
ecosystem.
ex: horse fly: Decompose organic matter
Honey bee: Pollinate flowering plants
6. Herbivores teeth are
flat so the can rip the
plants.
Carnivores teeth are
sharp so they can rip
the meat
If they try to change
their diet it could hurt
them. Like for instance if
a herbivore ate meat it
could hurt it and its
teeth could not rip the
meat. If a carnivore ate
plants it wouldn’t digest
good.
7. sun->seaweed->seal
-> polar bear
#1.
#2.
Sun->grass->rabbit>hawk
->vulture
4. List 4 different
possibilities that would
happen if one of the in
the food chain died
Go to question 7
If the seals died the
polar bears would too
2) If there was no sun the
seaweed would die so
would the seals and
the polar bears
3) If there were no polar
bears than the seals
would over populate
4) If the seals die than
the seaweed would
over populate.
1)
Seed- helps the flower reproduce
2. Flower- the color can worn predators
3. Leaf- makes the food and gets sun light
4. Stem- water and nutrients go up and back
down the steam
5. Roots- absorb the water and get nutrients
from the ground
1.
Question 10.
11. Some plant like
flowers need a lot of sun
light but trees need more
sun light because they
are bigger. Some plants
need different soil like
vegetables need soil that
don’t harm the
vegetable. They all need
the same amount of
nutrients trees might
need a little more
because they need it for
photosynthesis.
I.
II.
III.
Fly- they can disperse
better(pro). They can
also fly and plant next
to each other(con).
Carried- from a animal.
Can be carried to a
new habitat(con). They
can be carried and
drop in the right
habitat.
Eaten- animals can eat
them. Might not plant
(con). Animals might
not eat them.
13. Plant population
can decrease by…..
i.
Pollution
ii. No water
iii. No sun light
iv. No room to grow
v. Wrong habitat
14. Adaptations
 Scales
 Can climb
 Tall that can regrow
if it is cut off.
 Can blend in with
the sand to hide
from predators.
15.
Cactus’ adaptations:
Spines to protect it self
from predators. And
can hold water
Cactus’ niche:
Is to store water for the
camels and to protect
other animals.
16.
Plants- has oak and hickory trees
that absorb more water. In
addition there are American
Beech plants
Animals- the white tailed deer,
American Bald Eagle, etc..
Amount of sun light- varying
amount of sun light.
Spacing- a far amount of space.
 Extras- Temperature
 -30°C to 30°C, yearly average
is 10°C, hot summers, cold
winters
 Precipitation
 750 to 1,500 mm of rain per
year
17.
Organisms-Herbivorous
mammals like: lemmings,
voles, caribou, arctic hares
and squirrels
Carnivorous mammals like:
arctic foxes, wolves, and
polar bears
Adaptations of the animals
are that they ether have fat
or have thick fur to keep
warm.
