True or false: A species’ classification on the IUCN Red List is a complete measure of biodiversity in the ecosystem where it lives.
- A
True
- B
False
A conservation team needs a tool that classifies species’ risk of global extinction using defined criteria. What tool should it consult?
Complete the statement about interacting pressures: Fragmented habitat may make it harder for a species to as the changes.
A fishery wants to continue providing food over many years while reducing pressure on fish populations. Which approach best matches sustainable use?
- A
Harvest as much as possible whenever demand is high.
- B
Stop all use of biological resources in every location.
- C
Set science-based limits and use responsible practices so resources can be used over time.
- D
Use resources without monitoring because natural populations always recover.
True or false: An ecosystem with high biodiversity is automatically stable, regardless of its habitat condition and the disturbances it faces.
- A
True
- B
False
A region is designing a conservation program. Select all approaches that can strengthen its effectiveness or durability.
- A
Use repeated surveys to assess whether populations and habitats are improving.
- B
Assume that drawing a protected-area boundary guarantees conservation success.
- C
Protect or reconnect habitat where that addresses a conservation need.
- D
Include local and Indigenous communities in planning while respecting their rights and knowledge.
By 2030, what minimum percentage of degraded terrestrial, inland-water, coastal, and marine ecosystems does the global framework call for effective restoration of? Enter the percentage value.
A species is transported beyond its natural range and then harms native species in the new area. Which threat category best describes this situation?
- A
A native species that becomes more abundant after a rainy season.
- B
A species introduced beyond its natural range that harms native species or ecosystems.
- C
A species that naturally migrates into a nearby habitat without causing harm.
- D
A species that is rare in its native range but causes no ecological harm.
Complete the statement: Repeated surveys help determine whether populations and habitats are and whether conservation actions need to .
Select all examples of tools that can support conservation of species or genetic resources while complementing conservation in the wild.
- A
Seed banks
- B
Declaring a habitat protected without effective management
- C
Botanical gardens
- D
Captive breeding
A conservation team finds that individuals in one population differ in inherited traits, potentially affecting how the population adapts to environmental change. Which level of biodiversity does this describe?
- A
Species richness
- B
Ecosystem diversity
- C
Species evenness
- D
Genetic diversity
A landscape contains fragmented habitat, pollution affecting local species, and communities who depend on nearby biological resources. Propose a conservation plan that addresses each condition, explains how local communities should be involved, and describes how progress could be assessed and actions adjusted.
Two meadows each contain four species. In Meadow A, the species have similar numbers of individuals; in Meadow B, almost all individuals belong to one species. Which meadow has greater evenness?
- A
The meadow with most individuals belonging to one species
- B
The meadow with similar numbers of individuals in each species
- C
Both meadows equally, because they have the same number of species
- D
Neither meadow, because evenness depends only on habitat size
A population has substantial genetic variation. How might this variation help the population if environmental conditions change?
- A
It ensures every individual can survive any environmental change.
- B
It prevents environmental conditions from changing.
- C
It can increase the chance that some individuals have traits suited to new conditions.
- D
It makes all individuals in the population genetically identical.
The IUCN Red List provides a complete measure of biodiversity because it includes genetic diversity, species diversity, and ecosystem diversity.
- A
True
- B
False
A landscape contains forests, streams, and wetlands, along with their different communities and ecological processes. Which level of biodiversity does this variety describe?
Researchers want to compare species diversity in two habitats. Which approach makes the comparison most meaningful?
- A
Use similar sampling methods, area, and effort in each habitat.
- B
Sample one habitat much longer so its species list is more complete.
- C
Compare only the habitats with the greatest number of recorded individuals.
- D
Use different methods in each habitat to capture its unique conditions.
Unsustainable fishing removes organisms directly from a natural population. Which major direct driver of biodiversity decline does this represent?
A road divides a habitat into isolated patches, while local temperatures are shifting. How can these pressures interact to affect a species?
- A
Fragmentation prevents climate change from affecting local species.
- B
Fragmentation can make it harder for species to move as climate conditions shift.
- C
Climate change reconnects separated habitat patches by itself.
- D
The two pressures cannot affect the same species at the same time.
