Extinct

Answer 1

No individuals of a species are left on the Earth

Question 2

Conservation

Answer 2

protecting a natural environment to ensure that habitats are not lost.

Question 3

How does conservation help to increase biodiversity?

Answer 3

Protecting an organsism’s habitat increases that organism’s chance of survival, allowing them to reproduce and also preserves the relationships present in a habitat so populations of interlinked species are supported.

Question 4

Controlled grazing

only allowing animals to graze land for a certain period of time, giving plant species time to recover

Question 5

Captive breeding

What does captive breeding aim to do?

Answer 6

• Create a stable, healthy population of a species
• Gradually reintroduce the species into its natural habitat

Question 7

What are the disadvantages of captive breeding?

Answer 7

• Maintaining genetic diversity can be difficult since few breeding partners are available
• Organisms bornin captivity may not be suitable for release into the wild

Question 8

How is extinction being prevented in plants?

Answer 8

seed banks are being used so that new plants may be grown in the future should they go extinct

Question 9
