23.5 Measuring abundance and distribution (No Video)

What is biodiversity?

• The variety of organisms, species, and habitats in a particular area

• The study of human impact on the environment

• A measure of pollution in an area

• A type of ecosystem found only in tropical regions

Why is biodiversity important?

• It ensures the survival of human species

• It increases agricultural yield

• It is important for the aesthetics of nature

• It reduces the carbon footprint of an area

What does the term 'interdependence of species' refer to?

• Species living independently of each other

• Species competing for the same resources

• Species relying on each other to survive and reproduce

• The dominance of one species over another

What are the three main types of biodiversity?

• Forests, Deserts, Grasslands

• Mountains, Rivers, Oceans

• Climate, Water, Soil

• Species, Habitats, Genetics

What does species richness refer to?

• The number of individuals in a species

• The health of a species population

• The number of different species in a particular area

• The lifespan of species in an ecosystem

What is Simpson's Index used for?

• Measuring species biodiversity

• Calculating the age of a species

• Determining the water quality in habitats

• Estimating the population size of humans

What does genetic biodiversity refer to?

• The genetic similarity between different species

• The variety of ecosystems in a region

• The number of habitats available for colonization

• The variety of genes or alleles in a particular organism

How can genetic biodiversity be increased?

• Through habitat destruction

• Via random mutation and gene flow

• By introducing invasive species

• Through selective breeding

What is a consequence of a genetic bottleneck?

• Decreased genetic diversity

• Enhancement of species richness

• Stabilization of the ecosystem

• Increased genetic diversity

What is the purpose of using quadrats in sampling?

• To determine the depth of water bodies

• To calculate the height of trees

• To estimate population sizes or distribution of species

• To measure the speed of animals
