Biodiversity Brilliance Quiz

What does ecosystem diversity refer to?

• The variety of genes within a particular species

• The differences in physical appearance among individuals of a species

• The variety of habitats, natural communities, and ecological processes in the environment

• The number of species within a specific habitat

Which of the following best defines species diversity?

• The range of different habitats within a particular area

• The variety of ecosystems within a geographical location

• The diversity of genes within a population

• The variety of species within a community or ecosystem

Genetic diversity is crucial for:

• Increasing the uniformity of species

• Reducing the adaptability of species to changing environments

• Enhancing the resilience of ecosystems to environmental changes

• Decreasing the potential for natural selection

Which level of biodiversity is primarily concerned with the variation of traits within a species?

• Ecosystem diversity

• Species diversity

• Genetic diversity

• Community diversity

The number of different species in a given area is a measure of:

• Ecosystem diversity

• Species richness

• Genetic variation

• Ecological diversity

Why is ecosystem diversity important for human well-being?

• It ensures that all humans have the same genetic traits.

• It provides a variety of foods, medicines, and materials.

• It decreases the amount of oxygen in the atmosphere.

• It increases the rate of natural disasters.

A decrease in genetic diversity within a species can lead to:

• Increased resistance to diseases

• Decreased adaptability to environmental changes

• More rapid evolution

• A larger gene pool

Which of the following actions can directly increase species diversity in a region?

• Introducing non-native species

• Establishing protected areas

• Using pesticides extensively

• Clearing forests for agriculture

Genetic diversity is measured by:

• The number of ecosystems within a region

• The physical appearance of the species

• The variety of genes within a species population

• The number of species in an ecosystem

Which of the following is an example of ecosystem diversity?

• Different breeds of dogs

• Various types of forests, deserts, and lakes within a continent

• The number of insects in a rainforest

• The genetic variation within the wolf population
