Question 1

Which of the following best describes 'species diversity' as one of the three levels of biodiversity?

Accepted Answer

The number of species in an ecosystem, including endangered and threatened species.

Question 2

A conservation biologist is tasked with protecting a species that is declining due to habitat fragmentation. Which threat to biodiversity is most directly involved in this scenario?

Accepted Answer

Habitat destruction

Question 3

Which of the following is a benefit of biodiversity that directly supports human health?

Accepted Answer

Providing genetic resources for food and medicine

Question 4

Which approach to conservation focuses on the size of the population that begins to be affected by the extinction vortex?

Accepted Answer

Minimum viable population size

Question 5

A city plans to build a wildlife corridor to connect two forest reserves separated by a highway. What is the primary ecological benefit of this action?

Accepted Answer

Facilitating movement and gene flow between populations

Question 6

Which of the following is NOT a direct effect of human activity on the environment?

Accepted Answer

Increase in atmospheric oxygen levels

Question 7

Which of the following best explains why small populations are more vulnerable to extinction?

Accepted Answer

They experience lower reproduction and higher mortality.

Question 8

Which of the following is an example of an ecosystem service provided by biodiversity?

Accepted Answer

Production of antibiotics from soil microbes

Question 9

A population of frogs is declining due to increased UV radiation exposure after deforestation. Which two human activities are most likely contributing to this decline?

Accepted Answer

Deforestation and depletion of the ozone layer

Question 10

Which of the following best describes the 'declining population approach' in conservation biology?

Accepted Answer

Focusing on species that are already showing a downward trend in population size

Question 11

Which of the following is a likely consequence of habitat fragmentation?

Accepted Answer

Reduced population sizes and increased edge effects

Question 12

Which of the following is a sustainable development strategy that addresses climate change?

Accepted Answer

Energy decarbonization and sustainable industry

Question 13

During a warm period, which combination of solar-magnetic factors is most likely to occur?

Accepted Answer

High solar ray intensity and low cosmic ray intensity

Question 14

Which of the following is a direct result of increased greenhouse gas emissions?

Accepted Answer

Increased global average temperature

Question 15

Which of the following best describes the role of corridors in conservation biology?

Accepted Answer

They connect isolated populations, facilitating movement and gene flow.

Question 16

Which of the following is an example of how urban environments can influence evolutionary processes?

Accepted Answer

Urban environments can produce genetic and phenotypic shifts in organisms.

Question 17

Which of the following is a likely effect of the loss of ecosystem services due to reduced biodiversity?

Accepted Answer

Reduced pollination and food production

Question 18

Which of the following best explains why establishing protected areas is important for biodiversity conservation?

Accepted Answer

Protected areas provide habitats where species can persist with reduced human impact.

Question 19

Which of the following is a consequence of increased nutrient runoff from agriculture into aquatic ecosystems?

Accepted Answer

Eutrophication leading to oxygen depletion

Question 20

Which of the following is a key goal of sustainable development?

Accepted Answer

Meeting human needs while ensuring future generations can also meet theirs
