Annual rainfall
Decomposers
Rocks
3
Which is an effect of a keystone species?
breakdown structure
decrease stability
decrease diversity
increase stability
4
How can we tell if 2 organisms are part of the same species?
see if they live in the same ecosystem at the same time
see if they can breed together to have fertile offspring
see if they look the same
see if they eat the same things and build similar shelters
5
when one organism benefits and the other is not helped or harmed it's called:
parasitism
carnivorism
commensalism
mutualism
6
The study of how organisms interract with their environment
Zoology
Biology
Ecology
Climatology
7
The living things within an evironment
vertebrate factors
Ecological factors
Abiotic factors
Biotic factors
8
The global system that contains most of the life on earth is the
hydrosphere
atmosphere
geosphere
biosphere
9
If denitrifying bacteria are killed, where will the nitrogen build up in the nitrogen cycle?
soil
animals
plants
the atmosphere
10
organisms that can breed together to produce healthy babies are said to be of the same:
species
ecosystem
community
individual
11
If the birth rate is low, what is another way that the the population size can grow?
increase disease
increase the death rate
increase immigration
increase emigration
12
"trophic level" refers to:
an organisms specific role/niche in the environment
the flow of energy through a food web
how good of a predator an organism is
how large an organism is
13
Organisms that can make their own food
Herbivores
Heterotrophs
Autotrophs
Detritivores
14
when one organism benefits but the other organism is harmed
a sacrifice
parasitism
commensalism
mutualism
15
All of the following are heterotrophs except:
Carnivores
Algae
Omnivores
Decomposers
16
how can plants take up nitrogen
after it is fixed by special bacteria
directly from the air
straight from the soil
as water comes through roots
17
two species benefiting from living with each other is referred to as:
ketosis
mutalism
parasitism
commensalism
18
The greenhouse effect explains
how carbon is stored underground
how carbon has always been in the atmosphere
how the atmosphere traps heat
how the earth is cooling
19
How are biomes different than ecosystems?
Ecosystems are larger and greater influenced by weather
Biomes are larger and have common climate conditions
Ecosystems are smaller but are more impacted by the weather
Biomes share more common animal species than do ecosystems
20
Which of the following are considered biotic factors
Volcanic eruptions
Rocks
Rain
Scavengers
21
How foodwebs differ from food chains
chains are show the flow of matter
webs show multiple ways energy can flow through an ecosystem
webs are simpler
chains can show multiple ways energy can flow within a system
22
How much energy from one trophic level is available to the next trophic level?
10%
50%
5%
99%
23
where is carbon stored as a result of
photosynthesis
?
in mountains
in animals
in plants
in the air
24
Which of the following would be a secondary consumer in this food chain: algae -> small fish --> large fish --> shark?
shark
algae
large fish
small fish
25
In the water cycle,
transpiration
is...
uptake of water through the roots of a plant
evaporation of water through the stomata of plant leaves
rain, snow or hail
runoff water traveling along Earth's surface
26
What type of growth is being shown
standard growth
exponential growth
logistical growth
chain growth
27
All of these are density dependent factors regulating population growth except:
disease
all of them
food/water
space
28
What type of growth is being shown
chain growth
logistic growth
exponential growth
standard growth
29
Which organisms seek out once living (dead) matter to eat
autotrophs
scavengers
birds
herbivores
30
"Hydrosphere" refers to:
all living things on the planet
aquatic ecosystems
all the water on the planet
all the rocks and minerals on the planet
31
How does water leave the ocean to enter the atmosphere?
evaporation
transpiration
precipitation
runoff
32
The first organisms to populate a an area after a volcanic eruption are called
climax species
primary producers
keystone species
pioneer species
33
If most of the prey population dies due to a cold winter, how would the predator population be expected to change?
stay the same
Decrease more than usual
Increase
increase more than usual
34
Ecosystems are comprised of:
trees, grasses, deer, wolves, bugs, coyotes, bears
rocks, mountains, rivers, lakes, valleys, deserts
many ecological communities in different areas
populations and abiotic factors in one area
35
Primary succession occurs only when:
soil remains after a disturbance
after humans leave an area
new rock has formed
