Questions for Unit 2 from class Flashcards
The science concerned with preserving biodiversity is known as
Conservation Biology
What is the breakdown of the red threatened categories?
Critically Endangered
Endangered
Vulnerable
T/F- the US endangered species act has been successful, but the challenges consist of under budgeting, species are going extinct, and the continuous growth of species being added to the list each year
True
What type of biologist focuses on protecting individual species and maintaining or restoring entire ecosystems
Conservation Biologist
T/F- conservation biologists work to understand the threats facing species and ecosystems
True
Species that are at risk for extinction; various threat levels have been identified , ranging from least concern to extinct are known as
Threatened Species
T/F- Lemurs are endemic species to Madagascar
True
Species that live in a very small limited area are known as
Endemic Species
A species that is monitored to give deeper information about the ecosystem and its interactions is known as
Indicator Species
T/F- Indicator species require a unique niche or specific resources to survive
True
A species that has legal protections based its habitat is known as
Umbrella Species
T/F- by protecting sing species(umbrella species), we are able to extend those protections to more organisms in the area
True
T/F- With umbrella species, protecting northern spotted owls you also protect deer, rabbits, foxes, and etc in the area
True
Species that are interdependent on one another for survival is known as
Symbiosis
When both species benefit from an interaction this is known as
Mutualism
When one species benefits, and the other is not effected this interaction is known as
Commensalism
When one species benefits at the other species expense this interaction is known as
Parasitism
What are the two distinctions of symbiosis types?
Facultative and Obligate
Which symbiosis distinction means that the individual involved can use any individual not just one.
Facultative
What is an example of facultative
Clownfish living in a sea anemone, then dies. The anemone can just wait for another clown fish to arrive.
Which symbiosis distinction means that the two individuals are tied together and is reliant of a specific species
Obligate
What type of symbiosis relationship do whales and barnacles have?
Obligate commensalism
What could a decreasing wood stock population tell us about the community?
A) Increasing temperatures are affecting egg hatching rates
B) Wood stork prey populations are decreasing
C) Wood stork prey populations are increasing
D) Wood stork predator populations are decreasing
B) Wood stork prey populations are decreasing
T/F- A fundamental niche is not obtainable because this example shows their is only 1 species in the area that is able to fulfill its roles and that means they have no competition for food between a different species
True
