Question 1

Which of the following is NOT a major threat to biodiversity as identified by conservation biologists?

Accepted Answer

Natural selection

Question 2

Why is increasing genetic diversity important in conservation strategies?

Accepted Answer

It reduces the risk of inbreeding and increases population resilience.

Question 3

Which of the following best describes an ecosystem service provided by biodiversity?

Accepted Answer

The global value of $$33$$ trillion per year in ecosystem services

Question 4

A pharmaceutical company is searching for new drugs in tropical forests. This is an example of which benefit of biodiversity?

Accepted Answer

Medicinal resources

Question 5

Which of the following equations best represents the relationship between atmospheric CO$$_2$$ and global temperature over the long term?

Accepted Answer

$$T = k \cdot [CO_2$] + C$$

Question 6

What is a real-world consequence of excess nitrogen (N) in aquatic ecosystems, as seen in the Gulf of Mexico?

Accepted Answer

Hypoxia, leading to dead zones

Question 7

Which of the following is a direct effect of climate change on biological systems?

Accepted Answer

Coral bleaching

Question 8

If a conservation biologist wants to reduce the effects of habitat fragmentation, which strategy should they prioritize?

Accepted Answer

Providing connectivity between habitats

Question 9

Which of the following is an example of a restoration strategy in conservation biology?

Accepted Answer

Restoring ecosystems and managing habitats

Question 10

A region is experiencing more severe storms and increased drought frequency. Which global change phenomenon is most likely responsible?

Accepted Answer

Climate change

Question 11

Which of the following is a plausible reason why ecotourism is considered a benefit of biodiversity?

Accepted Answer

It provides significant economic value through wildlife-related recreation.

Question 12

Which of the following is a correct statement about the effects of acid rain?

Accepted Answer

It increases the acidity of precipitation, harming aquatic and terrestrial ecosystems.

Question 13

If the atmospheric CO$$_2$$ concentration in 2024 is 423 ppm and the global average temperature is 14.98°C, what trend does this data support?

Accepted Answer

Rising CO$$_2$$ levels are correlated with rising global temperatures.

Question 14

Which of the following is a real-life example of a species affected by global change?

Accepted Answer

Polar bears experiencing declining sea ice

Question 15

Which of the following best describes the economic value of ecosystem services?

Accepted Answer

$$33$$ trillion per year globally

Question 16

A city is deciding between building a water treatment plant for $$8$$ billion plus $$300$$ million per year in operating costs, or investing $$1$$ billion in land acquisition and education to protect a watershed. Which concept does this scenario best illustrate?

Accepted Answer

The cost-effectiveness of ecosystem services

Question 17

Which of the following is NOT a conservation strategy mentioned in the study materials?

Accepted Answer

Overharvesting resources

Question 18

Which of the following is a plausible multi-step approach to reduce inbreeding in a small population of endangered animals?

Accepted Answer

Introduce individuals from other populations and increase genetic diversity

Question 19

Which of the following is a likely outcome if invasive species are introduced into a new ecosystem?

Accepted Answer

Displacement of native species and reduced biodiversity

Question 20

Which of the following best explains why conservation biologists identify areas for protection?

Accepted Answer

To focus resources on regions with high biodiversity or at risk of loss
