• pop = total 1st x total 2nd / marked in 2nd

Question 3

Succession

Answer 3

• increased biodiversity
• gets to climax community

Answer 4

• grid
• random coordinates
• calculate frequency per quadrant
• calculate percentage cover
• large sample
• calculate average

Question 5

• stable populations and community

Question 6
