Imagine Aria, Charlotte, and James are on a thrilling adventure, studying the population of a mysterious bird species in their local forest. They discover that the population of this enigmatic species has plummeted by a staggering 80 to 90 percent over the past decade! How would our intrepid trio classify this species?

• Critically Endangered (CR)

• Endangered (EN)

• Vulnerable (VU)

• Near Threatened (NT)

Answer explanation

The question asks about the classification of a species that has witnessed a drastic population decline of 80 to over 90 percent in the last decade. The appropriate classification for such species is 'Critically Endangered (CR)'. This category is assigned to species facing an extremely high risk of extinction in the wild in the immediate future, which aligns with the given criteria.

Anika, Olivia, and Nora are on a thrilling adventure in the wild, studying for their biology exam. They stumble upon a mysterious stone tablet with a riddle about species conservation. The riddle reads, 'Which category of species, such as the majestic Amur Leopard or the mighty Sumatran Elephant, is teetering on the brink of extinction due to rapid population declines of 30 to more than 50 percent over the previous 10 years?'

• Critically Endangered (CR)

• Endangered (EN)

• Vulnerable (VU)

• Near Threatened (NT)

Answer explanation

The answer to the question is 'Vulnerable (VU)'. This category is applied to species which have faced rapid population declines of 30 to more than 50 percent over the previous 10 years, leading to a very high risk of extinction. The other options listed, while also categories of at-risk species, don't fit the specific criteria of the question.

Imagine Arjun, Jackson, and Priya are playing a game of 'Save the Species'. They come across a species that is close to becoming threatened or may meet the criteria for threatened status in the near future. Can you guess which category this species falls into?

• Critically Endangered (CR)

• Endangered (EN)

• Vulnerable (VU)

• Near Threatened (NT)

Answer explanation

The category of species that is close to becoming threatened or might meet the criteria for threatened status in the near future is 'Near Threatened (NT)'. This category isn't as extreme as 'Critically Endangered', 'Endangered', or 'Vulnerable', but it signifies that the species could potentially move into one of these categories if circumstances deteriorating their habitats or population continue.

Imagine Samuel, Isla, and Maya are on a thrilling adventure in a dense jungle. They come across a species that is pervasive and abundant after careful assessment. Can you guess how they would classify this species?

• Critically Endangered (CR)

• Endangered (EN)

• Vulnerable (VU)

• Least Concern (LC)

Answer explanation

The question asks about the classification for a species that is pervasive and abundant after assessment. Among the options given, 'Least Concern (LC)' is the correct choice because it is used for species that are widespread and abundant. 'Critically Endangered', 'Endangered', and 'Vulnerable' are classifications for species that are facing a higher risk of extinction.

Imagine Michael, Abigail, and Ava are on a thrilling adventure in a remote jungle. They stumble upon a mysterious creature. They want to categorize it, but they don't have enough data related to its risk of extinction. Which category should they apply to this creature?

• Critically Endangered (CR)

• Endangered (EN)

• Vulnerable (VU)

• Data Deficient (DD)

Answer explanation

The question asks about the category assigned to species when there's a lack of data regarding their risk of extinction. The correct answer is 'Data Deficient (DD)'. This category is used when there's insufficient information to make an assessment of its risk of extinction.
