Biodiversity

What does biodiversity include?

• Only ecosystem diversity

• Only genetic diversity

• Only species diversity

• Species diversity, genetic diversity, and ecosystem diversity

What is the main purpose of the Encyclopedia of Life project?

• To provide an accessible online library of worldwide species diversity

• To classify all living organisms into domains

• To explore unknown ecosystems

• To document all extinct species

Which of the following best describes species diversity?

• The classification of species into taxonomic groups

• The variety of ecosystems within a given area

• The genetic differences within a single species

• The number or variety of species in a particular region

What is the significance of genetic diversity within a species?

• It ensures all individuals are genetically identical

• It decreases the species' ability to survive environmental changes

• It reduces the species' vulnerability to diseases

• It provides the raw material for adaptation to local conditions

How are closely related species grouped in taxonomy?

• Into families

• Into domains

• Into species

• Into genera

What does the term 'subspecies' refer to?

• A group of unrelated species that share similar habitats

• A group of organisms that can interbreed and produce fertile offspring

• A population of organisms with genetically based characteristics that differ from other populations of the same species

• A classification above the species level

What can cause a local increase or decrease in species diversity?

• Genetic mutations

• Only extinction

• Only speciation

• Immigration and emigration

What is ecosystem diversity?

• The number and variety of ecosystems within a given area

• The genetic diversity within an ecosystem

• The number of species within a single ecosystem

• The classification of ecosystems into taxonomic groups

Which of the following is an example of a taxonomic group larger than kingdom?

• Genus

• Order

• Domain

• Phylum

Why is genetic diversity important for a population's survival?

• It increases the population's vulnerability to diseases

• It decreases the population's ability to adapt to local conditions

• It ensures all individuals are genetically identical, reducing conflict

• It enables populations to better cope with environmental change
