Conservation

Question 1

What is the purpose of seed banks

Answer 1

1. Store lots of seeds of different species
2. Store endangered species
3. If plant goes extinct in wild can be grown again

Question 2

What are two things seedbanks do?

Answer 2

1. Create cool, dry conditions for storage meaning they can be stored to long time
2. Testing viability (ability to grow)

Question 3

Name 5 advantage of seed banks

Answer 3

1. Cheaper storing seeds than grown plants
2. Large number in small space
3. Less labour
4. Can be stored anywhere rather than natural climate
5. Less likely to be damaged by disease, natural disaster or vandalism.

Question 4

Name 3 disadvantages for seed banks

Answer 4

1. Testing viability is expensive and time consuming
2. Too expensive to store all seed types
3. Can be difficult to collect seeds from remote locations

Question 5

What is the purpose of captive breeding programs

Answer 5

1. Breeding animals in controlled environment

2. Endangered or extinct (in wild) can be bred to increase numbers

Question 6

Name 2 problems with captive breeding programs

Answer 6

1. Animals can have problems breeding outside their natural habitat
2. Can be cruel to keep animals in zoos

Question 7

Why might organisms be reintroduced into the wild

Answer 7

1. Increase numbers in wild, helping to bring back from brink of extinction
2. Help organisms that rely on these plants for food
3. Contributes to restoring habitats

Question 8

What are 3 problems with reintroduction

Answer 8

1. Could bring new diseases to habitats, harming other organisms
2. Reintroduced animas may not behave as if raised in wild
3. People in area may not approve

Question 9

Name 3 ways seed banks can be contribute to scientific research

Answer 9

1. Can grow endangered plants for medical research or new crops without removing from wild
2. Study how plays can successfully grown from seeds, useful for reintroduction
3. Disadvantage: small interbred population not representative of wild plants

Question 10

How can zoos contribute to scientific research

Answer 10

1. Increase knowledge of behaviour, physiology and nutrition needs, contributes to conservation in wild
2. Can carry out research not possible in wild
3. Disadvantage that animals in captivity may act differently

Question 11

How can zoos and seed-banks educate people

Answer 11

Zoos: increase enthusiasm for conservation
Seedbanks: provide training and set up local seedbanks
