Biodiversity Quiz A level Cambridge

What is the definition of an ecosystem?

• A. A group of organisms with similar morphological and physiological features

• B. A relatively self-contained, interacting community of organisms, and the environment in which they live and with which they interact

• C. The role of an organism in an ecosystem

• D. The variety of species in an area along with their variation within species and the genetic diversity between them

What is the importance of maintaining biodiversity?

• A. Preventing extinction

• B. Providing new medicines

• D. All of the above

• C. Maintaining large gene pool

What is genetic diversity?

• A. The number of different species in the ecosystem and their relative abundance

• B. The diversity of the alleles within the genes in the genome of a single species

• C. The measure of the chance of a particular species being found in any one quadrant

• D. The measure of how many individuals there are per unit area

What is species diversity?

• D. The role of an organism in an ecosystem

• C. The variety of species in an area along with their variation within species and the genetic diversity between them

• B. The measure of the chance of a particular species being found in any one quadrant

• A. The number of species in a community

What is the purpose of random sampling in biodiversity studies?

• A. To determine species distribution in areas where conditions such as altitude, soil moisture content, pH or exposure to light intensity varies

• C. To find the highest value from the table

• D. To find the highest value from the table

• B. To calculate the diversity of organisms in a particular area

What is the purpose of systematic sampling in biodiversity studies?

• A. To determine species distribution in areas where conditions such as altitude, soil moisture content, pH or exposure to light intensity varies

• B. To calculate the diversity of organisms in a particular area

• D. To find the highest value from the table

• C. To detect changes in community composition along a line across one or more habitats

What is the purpose of Simpson’s Index of Diversity?

• A. To calculate the diversity of organisms in a particular area

• B. To determine species distribution in areas where conditions such as altitude, soil moisture content, pH or exposure to light intensity varies

• C. To estimate the population of mobile animals

• D. To find the highest value from the table

What is the purpose of correlation coefficient in biodiversity studies?

• A. To determine if there is a linear relationship and its strength

• B. To calculate the diversity of organisms in a particular area

• D. To find the highest value from the table

What is the purpose of Spearman’s rank correlation in biodiversity studies?

• C. To estimate the population of mobile animals

• B. To calculate the diversity of organisms in a particular area

• A. To find out if there’s a correlation when data is not normally distributed

• D. To determine species distribution in areas where conditions such as altitude, soil moisture content, pH or exposure to light intensity varies
