Topic 4: Biodiversity

Question 1

Describe the pros and cons of ex situ conservation [2]

Answer 1

• Pros: funds raised through entrance fees, memberships, and sponsorships can be used for further conservation efforts
• Cons: correct environmental conditions for survival may be difficult to achieve, and it may be expensive to maintain these conditions

Question 2

Describe the pros and cons of captive breeding programs [2]

Answer 2

• Pros: animals can be bred to increase the populations of endangered species
• Cons: animals may not behave as normal due to the unusual environment, so reproduction may be difficult

Question 3

Give two reasons why offspring from a captive breeding program may not be released into the wild [3]

Answer 3

• They are still needed for the captive breeding program
• Not enough suitable habitat/they would be at risk if released
• They are not prepared for reintroduction

Question 4

Explain why offspring from captive breeding programs may not be allowed to remain in the same facility [3]

Answer 4

• To prevent related animals from mating

-To prevent inbreeding depression

-To increase genetic variation within the species

Question 5

Explain why captive breeding programs are important for maintaining biodiversity [3]

Answer 5

• increase population size of species
  -maintain/increase genetic diversity
  -therefore prevents extinction of species

Question 6

Define “inbreeding depression”

Answer 6

the decrease or loss of fitness and strength which is mainly caused due to inbreeding
