Question 1

Which of the following best describes the three main components of biodiversity?

Accepted Answer

Genetic diversity, species diversity, and ecosystem diversity

Question 2

A region is considered a biodiversity hotspot if it meets which of the following criteria?

Accepted Answer

It contains at least 1,500 endemic plant species and has lost at least 70% of its original habitat

Question 3

Which of the following is the most significant threat to global biodiversity according to current scientific consensus?

Accepted Answer

Habitat destruction

Question 4

Why do some scientists prioritize the preservation of species from species-poor lineages?

Accepted Answer

Because losing these species would result in a disproportionate loss of evolutionary history

Question 5

Which of the following best defines an invasive species?

Accepted Answer

A non-native species that spreads rapidly and negatively impacts native ecosystems

Question 6

A scientist is studying a forest that has recently been fragmented by road construction. According to studies on habitat fragmentation, what is the most likely outcome for this forest?

Accepted Answer

A decrease in both biomass and species richness

Question 7

Which of the following is an example of an ecosystem service with direct economic value to humans?

Accepted Answer

Pollination of crops by bees

Question 8

Which of the following best explains why beef production is considered a 'resource hog'?

Accepted Answer

It requires large amounts of water, land, and feed compared to other protein sources

Question 9

Which of the following scenarios best illustrates the application of island biogeography theory to conservation planning?

Accepted Answer

Designing a network of large, connected reserves to maximize species richness

Question 10

Which of the following is NOT one of the six major threats to biodiversity?

Accepted Answer

Increased pollination by native bees

Question 11

A species is considered 'endangered' when:

Accepted Answer

It is at high risk of extinction in the near future

Question 12

Which of the following is a criticism of the biodiversity hotspot approach to conservation?

Accepted Answer

It may overlook regions with important ecosystem services but lower species richness

Question 13

Which of the following is the major threat to marine species?

Accepted Answer

Overexploitation (such as overfishing)

Question 14

Which of the following best describes the relationship between species richness and net primary productivity (NPP)?

Accepted Answer

High species richness generally increases NPP due to complementary resource use

Question 15

Which of the following would make preserving biodiversity almost impossible if it occurred?

Accepted Answer

Global loss of primary forests and widespread climate change

Question 16

Which of the following is an example of a real-world invasive species and its effect?

Accepted Answer

Zebra mussels in North America outcompete native mussels and clog water intake pipes

Question 17

Which of the following best describes an endemic species?

Accepted Answer

A species found only in a specific geographic area and nowhere else

Question 18

Which of the following conservation strategies is most effective for preserving genetic diversity?

Accepted Answer

Establishing large, connected reserves to allow gene flow between populations

Question 19

Which of the following best describes ecosystem function?

Accepted Answer

The sum of biological, geochemical, and physical processes that occur within an ecosystem

Question 20

A community is considered stable if:

Accepted Answer

It maintains its structure and function over time despite disturbances
