4.1.9 - Conservation Of Biodiversity Flashcards
When Species Go Extinct, What Does It Lead To?
A reduction in global biodiversity.
What Is Conservation?
Involves the protection and management of endangered species.
Ideally, Where Should A Species Be Kept For Conservation?
In their natural habitat, as all the support systems they need to maintain life already exist there.
What Are Examples Of Conservation Methods That Keep Species In Their Natural Habitat?
National and marine parks.
What Happens When It Is Not Possible To Keep Species In Their Natural Habitat?
Endangered species can be captured and placed in captivity for conservation efforts.
What Is An Example Of Conservation Efforts In Captivity?
Zoos.
What Are Some Scientific Methods To Ensure The Long-Term Survival Of Endangered Species?
Frozen zoos and seedbanks.
What Is A Seed Bank?
Conserves plant diversity by drying and storing seeds from different species in a temperature-controlled environment from the seeds of endangered plants.
What Happens If A Plant Species Goes Extinct?
Seeds from the seed bank can be used to grow the species again.
Why Are Stored Seeds Grown Into Plants After A Certain Period Of Time?
Seeds can only be stored for so long, so they are grown into plants to produce fresh seeds for storage.
What Does The Work Of Seed banks Involve?
(2 Points)
~ Creating cool, dry conditions needed for storage , so that seeds can be stored for a long time.
~ Testing seeds for viability as they can only be stored for so long.
What Are The Advantages Of Using Seedbanks?
(7 Points)
~ Cheaper to store seeds than fully grown plants.
~ Large numbers of seeds can be stored than fully grown plants as seeds need less space.
~ Less labour is required to look after seeds.
~ Seeds can be stored anywhere as long as its cool and dry.
~ Seeds are less likely to be damaged by disease, natural disasters or vandalism.
~ Valuable contributions to scientific research.
~ Provide a stock of endangered plants useful to humans, taking pressure off wild populations.
What Are The Disadvantages Of Using Seedbanks?
(3 Points)
~ Testing the seeds for viability can be expensive and time consuming.
~ To expensive to store all types of seeds and regularly test them for viability.
~ Could be difficult to collect seeds from some plants as they may grow in remote locations.
How Do Seed Banks Help Educate People?
(3 Points)
~ Educate about endangered species.
~ Increase interest in conserving species.
~ Train people to set up local seed banks, involving the community.
