Biodiversity Components

What is ecosystem diversity?

• Ecosystem diversity is the variety of different ecosystems within a specific area or region.

• Ecosystem diversity refers to the number of species within an ecosystem.

• Ecosystem diversity only considers the physical characteristics of an ecosystem.

• Ecosystem diversity is the same as genetic diversity.

Explain the importance of species diversity.

• Species diversity has no impact on ecosystems

• Species diversity is crucial for ecosystem stability, resilience, and the provision of ecosystem services.

• Species diversity only benefits a few select species

• Species diversity is irrelevant for conservation efforts

How does genetic diversity contribute to the survival of a species?

• Genetic diversity hinders adaptation to new environments

• Genetic diversity provides a wider range of traits for natural selection to act upon, increasing the chances that some individuals will survive and reproduce in changing conditions.

• Genetic diversity leads to inbreeding, which strengthens the species

• Genetic diversity increases competition among individuals, leading to extinction

What is the term used to describe the variety of genes within a species?

• genetic variation

• genetic diversity

• allele assortment

• gene pool

Define the term 'keystone species' and provide an example.

• An example of a keystone species is the sea otter, which helps maintain the health of kelp forests by controlling sea urchin populations.

• A keystone species is a type of rock formation that supports the structure of an ecosystem.

• An example of a keystone species is the common house cat, which plays a crucial role in maintaining biodiversity in forests.

• Keystone species are those that have no significant impact on their ecosystems.

Explain the concept of 'biodiversity hotspots'.

• Biodiversity hotspots are regions with high levels of biodiversity that are under threat from human activities.

• Biodiversity hotspots are regions with moderate levels of biodiversity.

• Biodiversity hotspots are areas with no threat to biodiversity.

• Biodiversity hotspots are regions with low levels of biodiversity.
