Reintroducing captive-bred animals into the wild is often complicated by their lack of natural:
- Inherent physical traits
- Foraging skills
- Reproductive biology
- Cellular structures
Explanation: Animals born in captivity often fail to develop vital survival behaviors, such as natural foraging skills or predator avoidance, making reintroduction difficult.
In situ conservation often prioritizes protecting a specific critical animal that heavily anchors the ecosystem, known as a:
- Exotic animal
- Extinct biological taxon
- Keystone species
- Weed
Explanation: Protecting a keystone species in situ inherently protects the vast web of other species that depend on it within that ecosystem.
Moving a locally extinct species from a zoo back into its historical natural protected habitat is termed:
- Complete habitat destruction
- Species reintroduction
- Culling
- Deforestation
Explanation: Species reintroduction bridges ex situ and in situ conservation by breeding animals in captivity and releasing them into protected wild habitats.
Because ex situ conservation isolates species from their natural predators and pathogens, captive populations often lose their:
- Natural defensive adaptations
- Captive breeding instincts
- Genetic cloning abilities
- Artificial selection traits
Explanation: Without the evolutionary pressure of natural predators and diseases, captive populations gradually lose their inherent physiological and behavioral defensive adaptations.
A major focus of botanical gardens is conserving plant species that are extinct in the wild, which is a form of:

Explanation: Unlike natural ecosystems which are self-sustaining, ex situ facilities like zoos and cryobanks require continuous human labor, electricity, and massive financial resources.
A major disadvantage of in situ conservation is that wild populations remain highly vulnerable to:
- Habitat destruction
- Genetic bottleneck
- Inbreeding
- Poaching
Explanation: Because the species remains in the wild, it is highly susceptible to habitat loss, climate change, and natural disasters.
What limits the capacity of botanical gardens to conserve high numbers of large, mature tree species?
- Pathogen exposure
- Soil toxicity
- Water shortages
- Physical space constraints
Explanation: Unlike seed banks which can store millions of genetics in a small freezer, botanical gardens require massive physical acreage to grow mature, living trees.
Seed banks preserve plant genetics by heavily reducing moisture and storing the seeds at:
- Ambient conditions
- Low temperatures
- Extreme heat
- Superheated environments
Explanation: Desiccating seeds and storing them at low temperatures significantly slows their metabolism, preventing germination and extending their viability.
In situ conservation strategies are highly dependent on the effective enforcement of strict:
- Captive breeding protocols
- Ex situ regulations
