1Chapter 13 Review Game Ecology Part One
2___________ is the study of the interactions
between organisms and their environment
ecology
3List the levels of ecological organization from
most broad to most narrow.
Biosphere, biome, ecosystem, community,
population, individual
4A group of different species that live together
in one area is a ____________.
community
5A(n) _________ includes all of the organisms as
well as the climate, soil, water, rocks, and
other nonliving things in a given area.
ecosystem
6A(n) ______ is a major regional or global
community of organisms.
biome
7The _________ is everywhere on earth where life
exists
biosphere
8What are the three approaches to conducting
ecological research?
Observing, experimenting, and modeling
9Which approach would be best to use in the
following research scenarioWhat are the effects
of global warming?
modeling
10Which approach would be best to use in the
following research scenarioHow does fertilizer
affect the number of blooms a pansy has?
experimenting
11Which approach would be best to use in the
following research scenarioHow often do rabbits
mate?
observation
12Which level of organization includes both living
and nonliving things?
ecosystem
13What is the difference between biotic and abiotic
factors?
Abiotic factors are nonliving parts of the
environment where as biotic factors are living
parts of the environment
14List two examples of abiotic factors that may
affect where a tree can grow
pH of soil, temperature, availability of water,
sunlight
15List two examples of biotic factors that may
affect where a squirrel can live.
Predator, prey(food), tree(habitat)
16________ is the variety of organisms in an
ecosystem
biodiversity
17In which biome is biodiversity the greatest?
Rain forest
18A _____________ __________ is a species that has
an unusually large effect on its ecosystem
Keystone species
19Why is a beaver an example of a keystone species?
By knocking down trees to build dams, beavers
change free-flowing stream habitats into ponds,
wetlands, and meadows. This modification leads to
many changes that ripple throughout the ecosystem.
20What is the main energy source for life on earth?
sun
21Compare autotrophs (producers) and heterotrophs
(consumers).
Autotrophs make their own food and heterotrophs
eat other organisms to get food
22Give two examples of an autotroph.
Plants, algae, some bacteria
23Give two examples of a heterotroph.
Cows, dogs, humans, earthworms, fungi, some
bacteria
24What are the two types of autotrophs?
Photosynthetic organisms and chemosynthetic
organisms
25What is the difference between photosynthetic
organisms and chemosynthetic organisms?
Photosynthetic organisms use sunlight to make
glucose whereas chemosynthetic organisms get
energy from the chemical bonds in inorganic
compounds
26List the five types of heterotrophs.
Herbivores, carnivores, omnivores, decomposers,
and detritivores
27What do herbivores eat? Carnivores? Omnivores?
Plants, animals, both plants and animals
28How do decomposers get their energy?
By breaking down organic matter
29From where do detritivores get their energy?
detritus
30________ is plant and animal remains and other
dead matter
detritus
31How is a food web different from a food chain?
A food web shows all of the feeding relationships
within an ecosystem (has multiple food chains)
32When drawing arrows in food chain or a food web,
in which direction should the arrow be drawn?
To show the flow of energy So, from the organism
that is being eaten to the organism that is doing
the eating
33Each step in a food chain or food web is called a
_______ _______.
Trophic level
34In the food chain plant?grasshopper?frog?owl,
label each of the organisms with one of the
following terms producer, primary consumer,
secondary consumer, tertiary consumer.
Plant? producer Grasshopper? primary
consumer frog?secondary consumer owl?tertiary
consumer
35In the food chain plant?grasshopper?frog?owl,
which organism is at the second trophic level?
grasshopper
36In the food chain plant?grasshopper?frog?owl,
label each of the organisms with one of the
following terms autotroph, herbivore, carnivore,
or omnivore
Plant?producer Grasshopper?herbivore Frog?carnivor
e Owl?carnivore
37What are the three types of ecological pyramids?
Energy, biomass, numbers
38An energy pyramid shows that as you move up
trophic levels in a food chain, the amount of
available energy at each trophic level _________
(increases, decreases) to only _____ of the
energy that was available at the previous trophic
level.
Decreases, 10
39Why is so much energy lost between trophic
levels?
Organisms use much of the energy that they
consume for life processes. Also, some of the
energy is released to the environment as heat
40____________ is the total amount of living tissue
within a given trophic level
biomass
41In a biomass pyramid, the biomass ________
(increases, decreases) as you move up trophic
levels in the food chain.
decreases
42Where is the greatest biomass in a biomass
pyramid?
at the base of the pyramid
43In a pyramid of numbers, the number of organisms
__________ (increases, decreases) as you move up
trophic levels.
decreases
44Matter cannot be created or destroyed instead it
is continually ___________.
recycled
45Water evaporates from the stomata of leaves
during ____________.
transpiration
46List three processes that release carbon dioxide
into the atmosphere.
Combustion of fossil fuels, cellular respiration,
decomposition of dead organisms
47What is one process that takes carbon dioxide
from the atmosphere?
photosynthesis
48What are two ways that humans are contributing to
the increase in carbon dioxide in the atmosphere?
Burning fossil fuels and destroying forests
49What is combustion?
Burning (in this case, the burning of fossil
fuels)
50How are fossil fuels formed?
when dead animal and plant materials are
compressed for millions of years and turns into
coal
51What do organisms use nitrogen for?
To build proteins
52During the process of _________, bacteria convert
ammonia to nitrates and nitrites
nitrification
53During the process of _________, bacteria convert
nitrates and nitrites to atmospheric nitrogen.
denitrification
54During the process of _________, bacteria convert
atmospheric nitrogen to ammonia.
Nitrogen fixation
55During the process of _________, plants absorb
ammonia, nitrates, and/or nitrites.
assimilation
56________ and ________ are released during
cellular respiration.
Carbon dioxide and water
57Plants use sunlight, _______ and _______ to
produce _______ during photosynthesis.
Carbon dioxide, water, glucose
58What is another name for the water cycle?
The hydrologic cycle
