Why do islands tend to have more specialist species than generalist species?
All of the above are reasons islands have more specialists than generalists
Generalist species have populations that are too large to live on islands
Generalist species aren't able to migrate to and colonize islands
Islands have fewer available food & habitat resources than mainlands
84
Autotrophs like plants &isomer bacteria make their own food, and are called...
Producers
Herbivores
Creators
Heterotrophs
85
What is it called when many adaptive radiations occur is a short period of time on Earth?
Speciation
Punctuated Equilibrium
Isolation
86
Combination of an organism's needs, habitat, and role it plays in its habitat is called?
Niche
Environment
Home
Population
87
Theory of Island Biogeography includes
larger habitats have less species
none of these
closer to other habitats = less species
closer to mainland leads to more species
88
Evolutionary change caused by humans is called?
Natural Selection
Artificial Selection
Variation Selection
89
Which of the following is an example of an anthropogenic activity that could disrupt a supporting ecosystem service?
All are anthropogenic activities that could disrupt a supporting service
Removal of native praries that contain wildflowers to build a highway
A fungal infection that spreads and reduces bee populations by 40%
A forest fire that burns down a stand of trees being logged for lumber
90
Which of the following is the best example of an exclusively natural (non-anthropogenic) ecosystem disturbance?
Flooding
Forest fires
Tornadoes
Disease
91
When an organism moves from one place to another.
Niche
Population
Survival of the Fittest
Migration
92
Wolves are a keystone species.
False
True
93
How does species richness relate to ecosystem resilience?
High species richness = high resillience
Species richness decreases as ecosystems recover from disturbances
Low species richness = high resillience
Species richness increases after environmental disturbances
94
Species that are early warnings of environmental damage are called
Indicator species
Specialist species
Keystone species
Native species
95
When some members of a species suddenly become cut off from the rest of that species.
Bottleneck
Isolation
Migration
Niche
96
Which of the following is not a provisioning ecosystem service of trees?
Lumber
Fruit
Oxygen
Filtration of ground water
97
Which of these is a keystone species
North American Beaver
White-Tailed Deer
Chow Chow
American Alligator
98
Habitat loss impacts generalist species more than specialist species:
False; habitat loss impacts generalists and specialists the same
False; generalists have fewer habitat needs & are more tolerant of change
True; generalist species have higher pop. sizes so they suffer more loss
True; generalists have more specific habitat needs and are less tolerant
99
Which of the following is NOT a key characteristic of pioneer species?
Fast growing
Tolerant of full sunlight
High soil nutrient requirements
Hardiness
100
Why Are Species Endangered?
Pollution
Deforestation
Hunting
Climate Change
