• because they contain a wide variety of trees and plants

- and these provide the food and shelter for lots of different animal species

Question 3

how does deforestation impact biodiversity

Answer 3

• it reduces biodiversity by removing tress
• which not only decreases the variety of vegetation, but the types of animal species that can live there
• either by chopping the trees down or burning them

Question 4

why do reforestation programmes need to be carefully planned

Answer 4

to maximise positive effects and minimise negative ones

Question 5

what is an example of effectively carrying out reforesation

- this will result in a higher biodiversity than replanting using only one type of tree

Question 6

Answer 6

• they help to protect biodiversity

- by preventing a species from dying out

Question 7

what are the four types of conservation methods

Answer 7

• protecting species in safe areas outside their natural habitat
• introducing captive breeding programmes
• using seed banks

Question 8

Answer 8

so the individuals have a place to live

Question 9

what is an example of protecting species in safe areas outside of their natural habitat

Answer 9

animals being protected in zoos

Question 10

what are seed banks used for

Answer 10

storing and distributing the seeds of rare and endangered species of plants

Question 11

what are the six benefits on both wildlife and humans when maintaining biodiversity on as local and global scale

Answer 11

• protecting the human food supply
• ensuring minimal damage of the food chains
• providing future medicines
• cultural aspects
• ecotourism
• providing new jobs

Question 12

why is protecting the human food supply a benefit of maintaining biodiversity

Answer 12

• over-fishing has greatly reduced fish stocks in the ocean

- conservation programmes will make sure that future generations will have enough fish to eat

Question 13

why is ensuring minimal damage to food chains a benefit of maintaining biodiversity

Answer 13

• if one species becomes extinct it will affect all organisms that eat and that are eaten by that species
• so the whole food chain is affected
• this means that conserving one species will help others to survive

Question 14

how does maintaining biodiversity provide future medicines

Answer 14

• many of the medicines we use today come from plants
• undiscovered plant species may contain new medicinal chemicals
• if these plants are allowed to come extinct like through forest destruction, we could miss out on valuable medicines

Question 15

Answer 15

• individual species may be important to a nations or areas cultural heritage
• the bald eagle is being conserved in the usa as it is regarded to be the nations national symbol
