Explanation / Answer

1. Immigration and emigration are the events that chage the species diversity globally. Option 1 is correct.

2. The Red List maintained by the World Conservation Union (IUCN) is a list of species threatened with extinction worldwide. Option 1 is correct.

3. Biodiversity enhances food security because it provides genetic diversity and the potential for developing more productive food crops that are disease resistant and adaptive to drought. Option 2 is correct.

4. In general, an organism that is successful as an introduced species will be subject to increases in the limiting factors it must deal with. Option 3 is correct.

5. According to E. O. Wilson, Biodiversity refers to genetic variants among a single species, individuals within a species, communities of organisms, and ecosystems. Option 2 is correct.

6. Taxonomists classify species using an organism's physical appearance and genetic makeup. Option 2 is correct.

7. The greatest diversity of organisms can be found among insects. Option 3 is correct.

8. The role of zoning is to classify areas for different types of development and land use. Option 2 is correct.

9. Habitat fragmentation, biodiversity protection, and the design and size of reserves are all aspects of the   reserve design plan. Option 2 is correct.

10. The equilibrium theory of island biogeography suggests that an island's number of species increases with the size of the island
