trees, shrubs, grasses, moss, lichen
grasses, moss, lichen, shrubs, trees
2
Which of the following would NOT affect natural selection?
Anthropogenic activities
Seasonal migration of species into or out of an area
Natural disasters like earthquakes, floods, climate change, fires, etc.
Location and movement of the continents.
3
Which of the following is NOT true about island biogeography?
Islands closer to the mainland tend to have higher biodiversity
Island biodiversity is similar to fragmentation of forests on land.
Islands closer to the mainland tend to have less biodiversity
Larger islands tend to have higher biodiversity.
4
Which of the following is NOT true in regards to disturbances?
Resilience is the ability to recover from a disturbance
Anthropogenic disturbances have decreased in frequency and intensity
Resistance is the ability to remain unchanged when a disturbance occurs.
Succession often occurs after a disturbance.
5
Which of the following limiting factors are NOT paired correctly?
Open ocean: Nitrogen
Soil: Salinity
Rainforest floor: Light
Freshwater lakes/rivers: Phosphorus
6
Which of the following is NOT paired correctly?
Experimental groups: change only ONE factor
Hypothesis: If/then statment predicts expected results in experiment
Control group: No change in independent variable allowing for comparison.
Independent variable: the effect measured and placed on the Y axis.
7
When a limiting factor such as nitrogen or phosphorus is in short supply algae blooms tend to happen.
True
False
8
Which of the following is NOT true about evolution?
Macroevolution is based on inference therefore it is open to debate.
Microevolution happens when natural selection promotes/elimates genes.
Microevolution has been seen within kinds of creatures.
Macroevolution is a fact, proven by observation and transitional fossils.
9
Which of the following is NOT true of primary succession?
An example would be changes after a forest fire.
An example would be changes on the bare rock after a volcanic eruption
It begins in an area where no soil is present.
It requires pioneer species like lichen and mosses to build soil.
10
Natural selection may promote resistance of a weed to a herbicide.
True
False
11
Which of the following are NOT paired correctly?
Support: pollination, water filtration, natural pest control
Intrinsic: Goods and services
Regulating: Removing carbon, cycling water and nutrients
Provisioning: Food, lumber, medicine
12
Which of the following is NOT true about an indicator species?
It gives early warning signs of damage or danger to a community.
They are not usually affected by pollution, droughts, or habitat loss
They may decline due to parasites, overhunting, or non native species
Examples include amphibians, birds, and butterflies.
13
Higher species EVENESS in an ecosystem (with the same species number\richness) means it has a higher biodiversity.
False
True
14
Which of the following does NOT describe species RICHNESS?
It affects biodiversity of an area.
The more kinds of species the higher the species richness.
It refers to the abundance of individuals within each species.
It refers to the total number of species in an area.
15
Which of the following would NOT describe an adaption?
It can be behavioral or physical trait that increases fitness.
It decreases the chances of survival in a species
It may be caused by natural genetic diversity or an added mutation.
It can allows a species to survice where many others cannot.
16
Which of the following is NOT true of a specialists species?
They tend to be more susceptible to disruptions in an ecosystem.
They include many amphibians, pandas, and koala bears.
They tend to decrease in number when fragmentation of habitat occurs.
They have a wider range of tolerance than generalist species
17
Massive flooding in the past created fossils, extinctions, fossil fuels, geological formations, and habitat destruction
False
True
18
Which of the following is a FALSE statement about biodiversity?
Biodiversity increases when adverse conditions, such as pollution, exists.
More species diversity allows quicker recovery after a disturbance.
A population with high genetic diversity responds better to stressors.
Biodiversity decreases when adverse conditions, such as pollution, exists.
19
Which of the following does NOT correctly describe a popultion bottleneck effect?
They can be caused by anthropogenic factors like clear-cutting/development
Bottlenecks can be caused by the introduction of an invasive species
Bottlenecks lead to decreased genetic diversity.
Bottlenecks lead to increased genetic diversity.
20
Which of the following is NOT considered an environmental stressor?
Natural disasters like fires, floods, storms, etc.
Long term stability in environmental conditions.
Temperature, light, moisture, and pH changes
Competition, predation, parasites, lack of mates
21
Which of the following ecosystem services includes tourism, real estate, and recreation?
Cultural
Regulating
Support
Provisioning
22
Which of the following is NOT true about a keystone species?
They have a small effect to community if removed
Their loss can cause an ecological cascade and population crash.
Examples include alligators, beavers, sea otters, and mangroves.
Their loss can cause extinction of other species disrupting entire food web
23
Limiting factors determine the carrying capacity of an ecosystem.
False
True
