Levels of Diversity

What is species diversity?

• Species diversity is the variety of different species within a specific ecosystem or area.

• Species diversity refers to the size of a particular species.

• Species diversity is the same as genetic diversity.

• Species diversity is the number of individuals within a species.

Why is species diversity important?

• Species diversity is important for ecosystem stability, resilience, and productivity, as well as for providing essential ecosystem services.

• Species diversity is only important for aesthetic reasons

• Species diversity has no impact on ecosystem stability

• Species diversity does not contribute to providing essential ecosystem services

How is species diversity measured?

• By analyzing the genetic diversity within a population

• By measuring the average size of individuals in a population

• Using indices like the Shannon-Wiener index, Simpson index, or species richness.

• By counting the number of individuals in a population

What are the three main components of species diversity?

• Species richness, species evenness, species dominance

• Species variety, species uniformity, species prevalence

• Species abundance, species distribution, species composition

• Species heterogeneity, species equilibrium, species control

What is the difference between species richness and species evenness?

• Species richness is the relative abundance of each species, while species evenness is the number of different species.

• Species richness is the number of individuals in a population, while species evenness is the number of different species.

• Species richness is the variety of habitats in an ecosystem, while species evenness is the number of different species.

• Species richness is the number of different species, while species evenness is the relative abundance of each species.

How does habitat destruction affect species diversity?

• Habitat destruction increases species diversity by forcing species to adapt

• Habitat destruction reduces available living space and resources, leading to a decline in population sizes and eventual extinction of some species, decreasing species diversity.

• Habitat destruction has no impact on species diversity

• Habitat destruction leads to an increase in population sizes and species variety

Give an example of a species-rich ecosystem.

• Arctic tundra

• Desert

• Coral reef

• Tropical rainforest

Explain the concept of species endemism.

• Species endemism occurs when a species is found in every part of the world.

• Species endemism is when a species is only found in urban areas.

• Species endemism is when a species is exclusively found in a particular geographic area.

• Species endemism refers to the migration of species across different continents.

What role does species diversity play in ecosystem stability?

• Species diversity leads to decreased productivity in ecosystems

• Species diversity increases resilience to environmental changes, enhances productivity, and promotes overall ecosystem health.

• Species diversity has no impact on ecosystem stability

• Species diversity decreases resilience to environmental changes

Discuss the impact of invasive species on species diversity.

• Invasive species can reduce species diversity by outcompeting native species, preying on them, introducing diseases, and altering habitats.

• Invasive species promote species diversity by reducing competition

• Invasive species increase species diversity by providing new habitats

• Invasive species have no impact on species diversity
