Scientist have determined that the early Earth had no free oxygen anywhere. Briefly explain what evidence in
the rock layers that scientists found to prove when the early conditions on earth had free oxygen in the
atmosphere.
Answer the following question.
The graphs show how the cloudiness of the water at two
different sites varied over a period of one year. Site A had a low nitrate
concentration. Site B had a high nitrate concentration.
(i) Describe and explain the effect of increased nitrate concentration on algal
growth.
(ii) Algae do not live long. Explain why the presence of large numbers of algae
results in a fall in the amount of oxygen dissolved in the water.
(iii) There are very few submerged water plants at Site B. Use
(iii)
the graphs to suggest how placing a speed limit on boats might allow
submerged water plants to become re-established at Site B.

- Dead organic matter commonly decomposes in a pattern that follows a negative exponential curve. Scientists wanted to compare the decomposition rates of leaves from cherry trees and maple trees. The scientists placed bags of leaves from each type of tree into a stream and retrieved the bags over time. The scientists repeated the experiment three times. The scientists calculated and graphed the mean amount of litter remaining of each leaf type at all time points. When plants decompose, the dead plant matter first leaches substances such as salts, sugars, and amino acids. After this leaching, one compound left behind is lignin. Lignin gives leaves their toughness and resists decomposition. Leaf mass remaining (grams) 1004 75+ 50- 25- O 25 50 75 Time (days) Maple Cherry 100 Select the statement the data support about the rate of leaf decomposition and the amount of lignin present in leaves.
