A. Burning smaller areas causes a greater increase in biodiversity than burning larger areas.

B. Burning larger areas causes a greater increase in biodiversity than burning smaller areas

C. Burning smaller areas causes a decrease in biodiversity compared to burning larger areas.

D. Burning larger areas causes a decrease in biodiversity compared to burning smaller areas

Answer 2

From....what i understand of the graph, the larger the area of the burns, the greater the increase in biodiversity.

Answer 3

It's cutting back the pine tree population and allowing the shrub population to grow back, while not entirely letting either species dominate the area (the way the pine tree was)

Answer 4

It's B correct ?

Answer 5

Should be.

Answer 6

Use the information on the above PDF document along with your knowledge of science to answer the question.

PART B: Which statements about Graph 1 are evidence that supports the answer to Part A?

A. The slopes of the data lines reverse from the largest scale to the smallest scale of plot size


B. The slopes of the data lines become more steep as the scale of the plot size decrease


C. The slopes of the data lines become more steep as the scale of the plot size increases


D. The slopes of the data lines are all negative at all three scales of plot size


E. The slopes of the data lines become less steep as the scale of the plot size increases


F. The slopes of the data lines become less steep as the scale of the plot size decrease

Answer 7

C and F

Answer 8

Use the attached picture of graph and your knowledge of science to answer the question.

Which statements best explain what the data in Graph 2 and the images of the different management practices show about increasing the biodiversity of herbs and grasses?

Select the THREE correct answers:

A. The effects of thinning pine trees and woody shrubs are greater in unburned areas than in burned areas


B. The thinning of pine trees in burned areas had a slightly greater effect on the biodiversity of herbs and grasses than the thinning of woody shrubs in Year 8, but that effect decreased by Year 14


C. The effects of thinning pine trees and woody shrubs are much greater than the effects of burning alone


D. The continued thinning of pine trees in burned areas has a much greater effect on the biodiversity of herbs and grasses than the thinning of woody shrubs doe


E. The effects of thinning pine trees on the biodiversity of herbs and grasses in burned areas, compared to the effects of thinning of woody shrubs, is about the same over time

Answer 9

I'm not.....entirely sure I'm reading this graph correctly. @Shadow could you check for me please?

Answer 10

From what it looks to me, the number of species has hardly changed, so I'd pick.... A B, and E....?

Answer 11

yes

Answer 12

Based on the data from the two studies and your knowledge of stability and change in ecosystems, develop a management plan for restoring plant biodiversity in a 1-km2 longleaf pine ecosystem. In your plan, describe two steps that should be taken, and explain how each step will affect plant biodiversity. Use evidence from the information provided on longleaf pine ecosystems to support your answer
