If an island is closer to the mainland, how will this impact the biodiversity?
There will be a higher level of biodiversity here than an island that is further away.
There will be a lower level of biodiversity here than an island that is further away.
There will be no difference in biodiversity on islands based on distance to mainland.
Which of the following is NOT a factor that impacts ecological tolerance?
Temperature
pH
Humidity
Level of biodiversity
What is ecological succession?
A set of environmental conditions within which an organism can best survive
An organism's ability to adapt to its environment
A peak community where the organisms are stable
The process of change in the species structure of an ecological community over time
What stage of ecological succession is being shown?
Primary succession
Secondary succession
Tertiary succession
Climax community
Which of the following is NOT considered to be a natural disruption to an ecosystem?
Volcanic eruption
Hurricane
Air pollution
Earthquake
Which ecosystem is the most biodiverse?
Temperate deciduous forest
Tropical rainforest
Boreal forest
Savanna
When a community is stable with little to no change, what level of ecological succession is taking place?
Primary succession
Secondary succession
Tertiary succession
Climax community
Which of the following is NOT a type of ecosystem service?
Cultural
Regulating
Recreational
Provisional
What is the difference between primary and secondary succcession?
Primary succession already has soil
Lichen and moss come in for secondary succession
Secondary succession already has soil
Climax community is achieved quickly in primary succession
Which is true of the location above?
It has low species richness
It has low species evenness
It has high species evenness
It has both low species evenness and richness
None of these
The main cause of biodiversity loss worldwide is
extinctions
invasive species
pollution
habitat destruction
Introduced species can become pests because they;
Produce only a few young after a long period of gestation.
Inhabit only niches that have recently become available after the local extinction of another species.
Can live in many niches, easily adapting to many variables and eating a wide variety of food.
Have a low genetic variability, enabling them to live in a wide variety of habitats.
Increase biodiversity because they attract more species to the areas in which they settle.
The aesthetic value of an ecosystem provides
a supporting service.
a regulating service.
an intrinsic value.
a cultural service.
When a spruce tree is harvested so the wood can be used to build a house, the tree is providing
a cultural service.
a provision.
an intrinsic value.
a monetary unit.
Human waste is often dumped in the ocean. Microbial organisms in marine ecosystems can break down organic waste into less harmful components. This is an example of
a cultural service.
an ecosystem provision.
a regulating service.
an intrinsic value.
Which of the following is an example of a keystone species?
Beavers
Elephants
Kudzu vine
Sea otters
Which of these is an aquatic indicator species?
Shrimp
Coral
Plankton
Sea Anemone
Which of the following is not a terrestrial indicator species?
Birds
Crocodile
Insects
Amphibians
Match the organisms with their role in the ecosystem

Kudzu vine- keystone, beaver- invasive, sea otter- keystone
kudzu vine- foundation, beaver- keystone, sea otter- invasive
kudzu vine- invasive, beaver- foundation, sea otter- keystone
Which of the following statements is true?
Primary succession is followed by secondary succession
Primary succession occurs over a shorter time span
Forest fires and hurricanes lead to primary succession because a soil base still exists
Volcanoes creating igneous rock formations lay based for primary succession to take place
Why are sea otters so crucial to an ecosystem?
They aren't.
They build dams and help rivers flow
They provide us with nutrients
They feed on sea urchins which are harmful to kelp forests
Pioneer species like moss and lichen are most likely to show up after
primary succession
secondary succession
Organisms that make physical changes and help create habitats are known as
Invasive species
Keystone species
Foundation species
Endangered species
Which of the following is true about island biodiversity?
Small islands are more likely to have more immigrated species
Small islands have more biodiversity
Small islands have more species
Small islands have less resources
What is the difference between primary and secondary succcession?
Primary succession already has soil
Lichen and moss come in for secondary succession
Secondary succession already has soil
Climax community is achieved quickly in primary succession
What prediction is correct about island biogeography?
Smaller islands have more resources, and will have more biodiversity
Larger islands have more space for resources, but will have less biodiversity due to competition
Animals Islands closer to mainland will migrate successfully and there will be more diversity
Animals will fly to far away mainland and there will be more diversity
The number of species in a community...
species richness

Distribution of abundance across the species in a community...
species richness

According to the theory of island biogeography, what condition promotes the acceleration of the extinction rate of species on an island?
the island is small and far from the mainland
the island is small and near the mainland
the island is large and far from the mainland

Which conditions would likely promote the immigration of new tree species to an uninhabited island?
a small island that is near the mainland
a small island that is distant from the mainland
a large island that is near the mainland
a large island that is distant from the mainland
