Biodiversity Review

What is the main goal for conservation according to the passage?

• Maintaining biodiversity on our planet

• Increasing the abundance of species

• Reducing human impact on coastal habitats

• Enhancing species richness

How is species richness defined in the passage?

• The number of individual organisms in a specific area

• The number of species found within a set area

• The evenness of species distribution

• The abundance of species in a habitat

What role do mussels play in coastal habitats according to the passage?

• They serve as ecosystem engineers

• They increase the abundance of fish

• They reduce wave impact on the shore

• They provide food for larger predators

Which of the following is NOT a factor measured to understand biodiversity in the passage?

• Species richness

• Abundance

• Evenness

• Habitat size

What question did the scientists from Canada and Argentina aim to answer?

• Does the biodiversity among mussel beds differ between wave exposed and wave sheltered habitats?

• How do mussels affect the abundance of fish in coastal habitats?

• What is the impact of human activity on coastal biodiversity?

• How does species richness vary with temperature changes?

What kinds of sites were used for sampling in the study?

• Sites that were sheltered and sites that were exposed to wave action

• Only sites exposed to open-ocean waves

• Sites with partial mussel bed coverage

• Sites with high human activity

How is evenness calculated according to the passage?

• By dividing the number of species by the size of the area sampled

• By dividing Shannon’s diversity index by the natural logarithm of species richness

• By counting the number of individual organisms

• By measuring the abundance of species
