Ecology Quiz Review Answer Key
1.) The
2.)
Sun
is the original source of almost all energy used by living things.
Ecology
is a branch of science that studies living things and their interactions with
their nonliving environment.
3.) The surface of the Earth & all of the ecosystems is known as the
ecosphere
.
4.) Place a circle around the biotic factors and a rectangle around the abiotic factors below.
soil
mushroom
grass
bacteria
wind
5.) All organisms have a range of
temperature
shark
sunlight
tolerance
water
for each abiotic factor.
6.) When plants move towards the light as they grow it is called
7.)
humans
phototropism
.
Endotherms
are warm-blooded animals that attempt to control over their body
temperature, while cold-blooded animals must have the same body temperature of their
environment and are called
ectotherms
.
8.) Place a circle around the endotherms and a rectangle around the ectotherms shown below.
human
mouse
lizard
snake
bluejay
9.) Endotherms and ectotherms both have some advantages. While endotherms can maintain
steady body
temperature
get sick less often and require less
and can be active in different climates, ectotherms
energy
than endotherms.
10.) If a warm-blooded animal’s temperature rises too high it can lead to
and if its temperature falls too low it can lead to
hypothermia
hyperthermia

11.) Some adaption plants have to live in dry environments include small
that can open and
close
, deep or widespread
roots
leaves
, or very thick
, stomata
cuticles
12.)
Wind
is an abiotic factor that can help animals smell predators and cool down. It
can also help pollinate plants.
13.)
Biogeochemical
cycles are the recycling of important elements such as carbon,
hydrogen, oxygen, nitrogen, and phosphorous.
14.) During the water cycle, when water moves out of tree leaves and into the atmosphere it’s
called
transpiration
. After water condenses and falls to Earth as precipitation
it will move slowly through the soil in a process known as
15.) The two main processes of the carbon cycle are
chloroplast in plants and cellular
respiration
infiltration
.
photosynthesis
done by the
done by the mitochondria in
both plants and animals.
16.)
Bacteria
in the soil play a key role in the biogeochemical cycling of nitrogen.
17.) The weathering of rocks play a key role in the biogeochemical cycling of
18.) Bodies of water are classified as either oligotrophic,
mesotrophic
Deep, clear bodies of water with low levels of nutrients are known as
19.)
Eutrophication
phosphorous .
, or eutrophic.
oligotrophic
.
occurs when excessive nutrients enter a body of water (often
from overuse of fertilizers). This leads to the overproduction of algae which can deplete
oxygen levels in the water. This low oxygen condition is known as
cause a significant depletion in the fish population.
anoxia
