This quiz contains 10 questions from a mix of 1 subtopics.
Which of the following best describes a habitat?
a relatively self-contained, interacting community of organisms and their environment
the place where a species lives within an ecosystem
the living organisms of all species found in a particular ecosystem at a particular time
the variation in alleles within a population of a species
|
Which of the following is true about species richness?
(Select all that apply)
it is quantified by taking random samples and counting the number of species present
it is the similarity in population size of each species
a higher species richness indicates greater diversity
it is measured by taking samples and counting individuals of each species
|
Which of the following is true about species evenness?
(Select all that apply)
it is quantified by taking random samples and counting the species present
it is the total number of different species in a habitat
a higher species evenness indicates lower diversity
more even abundances mean higher species evenness and diversity
|
In the diversity index equation, what does the variable 'N' represent?
the diversity index value
the number of species
the number of individuals of each species
the total individuals of all species
|
In the diversity index equation, what does the variable 'n' represent?
the diversity index value
the total number of all individuals
the number of species
the number of individuals of each species
|
Which of the following is NOT a way to compare genetic diversity?
comparing the base sequence of DNA
comparing the number of individuals in each species
comparing the amino acid sequence of the proteins encoded by DNA and mRNA
comparing the frequency of measurable or observable characteristics
|
Which of the following best describes an ecosystem?
a relatively self-contained, interacting community of organisms and their environment
the variation in alleles within a population of a species
the place where a species lives within an ecosystem
the living organisms of all species found in a particular ecosystem at a particular time
|
What does a higher value of the diversity index (d) indicate?
higher diversity
equal diversity
no relation to diversity
lower diversity
|
Which of the following is true about high genetic biodiversity?
(Select all that apply)
it increases resistance to disease
it allows for better adaptation to a changing environment
it increases the risk of extinction
it decreases the ability to adapt to environmental changes
|
Which of the following best describes a community?
the living organisms of all species found in a particular ecosystem at a particular time
A relatively self-contained, interacting community of organisms and their environment
the variation in alleles within a population of a species
the place where a species lives within an ecosystem
