Less competition

Question 20

How do you measure biological diversity?

Answer 20

We can use diversity index

Question 21

Natural selection

Answer 21

• not all offspring survive
• many variations within a species
• variations increase the chances of an organism surviving to reproduce
• variations are passed on and lead to changes in the genetic characteristics of a species
• nature determines which animals and plants will be able to reproduce and spread their characteristics

Question 22

Artificial selection

Answer 22

• used to increase a single trait or combine two or more traits
• also called selective breeding
• involves picking the animals with the traits that you want and breeding them with another, the offspring will have the parents traits
