1

All of the members of a single species living in an area is called a:

community

ecosystem

population

biome

1

Which is an abiotic factor in a forest ecosystem?

earthworm

mushroom

rainfall

all of the above

1

Lichens are often the first organisms to colonize an area during primary succession. Lichen is an example of:

a pioneer species

a tertiary consumer

a rock

secondary succession

1

Following a forest fire, which type of succession will occur?

primary, because the fire destroyed all the plants

primary, because the animals left during the fire

secondary, because the fire likely killed most of the animals

secondary, because there is still soil following the fire

1

Which biome would you expect to have the most primary productivity?

Tundra

Taiga / Boreal Forest

Tropical Rainforest

Desert

1

In an ecosystem, which term correctly describes an oak tree?

autotroph

heterotroph

decomposer

detritivore

1

Leaf --> Grasshopper --> Robin --> Cooper's Hawk
In the food chain above, which is a secondary consumer?

Leaf

Grasshopper

Robin

Cooper's Hawk

1

Berry --> Robin --> Cat
If this food chain and the food chain from question 7 were in the same habitat, what is the robin?

herbivore

carnivore

omnivore

detritivore

1

Which best describes the relationship between energy and trophic level?

There is more available energy for consumers at higher trophic levels

Each step up the food chain results in a 90% loss of available energy

10% of energy from the producers is available to all levels of consumers

all of the above

1

Which two steps of the water cycle increase the amount of water vapor (gas phase of water) in the atmosphere?

condensation, precipitation

evaporation, condensation

transpiration, precipitation

evaporation, transpiration

1

What is the process called in which water moves into the ground and accumulates in aquifers?

percolation

transpiration

condensation

photosynthesis

1

Which process increases the amount of CO₂ in the atmosphere?

denitrification

transpiration

combustion

photosynthesis

1

In the carbon cycle, what is the result of respiration?

Increased CO₂ in the atmosphere

Decreased CO₂ in the atmosphere

Increased glucose in the atmosphere

Decreased glucose in the atmosphere

1

Which organisms play a significant role in most steps of the nitrogen cycle?

secondary consumers

bacteria

plants

all of the above

1

What is nitrogen fixation?

The conversion of useful forms (to plants) of nitrogen back into atmospheric nitrogen

The conversion of atmospheric nitrogen to more useful forms (to plants) of nitrogen

Nitrogen moving into animals from plants

Nitrogen leaving animals in the form of urine

1

Which statement is true regarding an organism's niche?

A fundamental niche is always bigger than a realized niche

A realized niche is usually smaller than a fundamental niche due to competition from other species

In most species an individual's niche is unique and cannot be applied to other members of its species

all of the above

1

In which form of symbiosis do both species benefit?

mutualism

commensalism

parasitism

none of the above

1

Gobies (a type of fish) and a species of shrimp with very poor eyesight will often form a symbiotic relationship in which the shrimp digs a whole in which they can both hide from predators, while the Goby watches for predators and alerts the blind shrimp of any danger. This is an example of:

mutualism

commensalism

parasitism

predation

1

Which is true of an invasive species?

They are introduced into an ecosystem (often unintentionally) from somewhere else

Their populations often grow quickly due to lack of natural predators and competition

They typically have an overall negative impact on the health of an ecosystem

All of the above

1

Which situation will lead to a growing population?

birth rate is greater than death rate

emigration is higher than immigration

death rate is greater than birth rate

a deadly contagious disease enters the population

1

In which type of growth is the population size limited by carrying capacity?

logistic

exponential

both of the above

none of the above

1

Which is true of carrying capacity?

The carrying capacity of an ecosystem cannot change

A decrease in food availability will usually increase the carrying capacity for a species

All ecosystems have the same carrying capacity

Carrying capacity for any species fluctuates based on available resources and competition

1

Which type of species is most likely to dramatically overshoot carrying capacity?

r-strategists because they reproduce quickly resulting in exponential growth

r-strategists because they reproduce slowly resulting in logistic growth

k-strategists because they reproduce quickly resulting in exponential growth

k-strategists because they reproduce slowly resulting in logistic growth
