Biodiversity

Choose the correct types of biodiversity.

I. Interaction diversity

II. Species diversity

III. Ecosystem diversity

• I and II

• I and III

• II and III

• I, II and III

'' The differences between living organisms within a species.''

This statement refers to which type of diversity?

• Genetic diversity

• Ecosystem diversity

• Interaction diversity

• Species diversity

How do you define 'biodiversity'?

• Biology

• Living organisms

• Variety of living organism

• Interaction between living and non-living organism

The most important component of biodiversity is:

• Species diversity

• Genetic diversity

• Habitat diversity

• All of the above

Low genetic diversity is characteristic of:

• Populations with a wide distribution

• Populations that have experienced bottleneck evens in their history

• Endemic species

• Coastal populations

Ecosystem resilience refers to:

• The unchanging nature of ecosystems over time

• The ability to recover from external disturbances

• Ecosystems with high diversity

• A steady state of community biomass

The graph shows that:

• Pisaster causes a decline in species richness

• Species richness declines when Pisaster is removed

• Pisaster is a predator

• There is a maximum of 20 species in this ecosystem

Refer to the graph. The results of this experiment indicate that:

• The presence of Pisaster has no effect of community diversity

• The ecosystem has high diversity

• The ecosystem has low diversity

• Pisaster is a keystone species

Numbers different invertebrate species at four sites in a stream (per m2 of stream bed sampled). The invertebrate diversity at 4 sites in a stream that had suffered a moderate effluent spill 2 weeks before sampling. Which sequence represents the position of the sites from the closest to the furthest from the spill?

• 1->2->3->4

• 1->4->3->2

• 2->3->4->1

• 1->3->4->2

There are three levels of biodiversity that are observed in nature and studied worldwide.

The first level is ____ diversity, which refers to the variety of habitats, ecosystems, and ecological processes.

The next level is ____ diversity, which refers to variability between populations of species and between different species.

The third level is ____ diversity, which refers to the variability of genes within a population

• ecosystem, species, genetic

• genetic, ecocystem, species
