A grassland ecosystem has a Simpson Index of 0.6. Explain how this value reflects the biodiversity of the ecosystem.

• The Simpson Index of 0.6 reflects a relatively high level of biodiversity in the grassland ecosystem.

• The Simpson Index of 0.6 reflects a lack of biodiversity in the grassland ecosystem.

• The Simpson Index of 0.6 reflects a low level of biodiversity in the grassland ecosystem.

• The Simpson Index of 0.6 reflects a moderate level of biodiversity in the grassland ecosystem.

Explain the role of Simpson Index in measuring the diversity of a forest ecosystem.

• The Simpson Index measures the diversity of a forest ecosystem by considering the age of the trees in the forest

• The Simpson Index measures the diversity of a forest ecosystem by taking into account the number of different species present and their relative abundance.

• The Simpson Index measures the diversity of a forest ecosystem by counting the number of trees in the forest

• The Simpson Index measures the diversity of a forest ecosystem by looking at the size of the leaves on the trees

Discuss the relationship between habitat destruction and the Simpson Index.

• Habitat destruction can lead to a decrease in species diversity, which in turn can affect the Simpson Index.

• Habitat destruction increases species diversity and improves the Simpson Index

• Habitat destruction has no impact on the Simpson Index

• The Simpson Index is not affected by habitat destruction

Explain how the introduction of an invasive species can affect the Simpson Index of an ecosystem.

• The Simpson Index increases due to increased diversity caused by the invasive species.

• The Simpson Index remains unchanged regardless of the invasive species.

• The Simpson Index decreases due to reduced diversity caused by the invasive species.

• The Simpson Index fluctuates randomly with the introduction of an invasive species.

How does the size of a habitat influence the Simpson Index of the community?

• The Simpson Index is higher in smaller habitats and lower in larger habitats

• The Simpson Index is only influenced by the number of species, not the size of the habitat

• The size of a habitat has no impact on the Simpson Index

• The size of a habitat can influence the Simpson Index by affecting the diversity and abundance of species within the community.

What is the impact of climate change on the Simpson Index of a marine ecosystem?

• It can cause the Simpson Index to remain constant regardless of changes in species diversity and abundance.

• It can increase the Simpson Index due to changes in species diversity and abundance.

• It has no impact on the Simpson Index.

• It can decrease the Simpson Index due to changes in species diversity and abundance.
