A researcher hypothesis that in the Alaskan tundra area in the study shrubs will dominate the landscape in later succession stages make a claim based on evidence in the graph to support or refute this hypothesis

A) Based on the information in the graph, identify the percent of cover for mosses in the unburned plot.
b) Based on the information in the graph, identify the dominant groundcover in the plot where a fire occurred 32 years before the data were collected. c) Based on the information in the graph, describe the percent coverage of sedges and grasses in the unburned plot compared to that in the plot burned most recently.
(d) A researcher hypothesizes that in the Alaskan tundra area in the study, shrubs will dominate the landscape in later succession stages. Make a claim based on evidence in the graph to support or refute this hypothesis. e) Lichen have become extinct in large areas since the Industrial Revolution. Lichen are sensitive to sulfur dioxide because they can quickly and efficiently absorb the sulfur from the atmosphere. Describe how lichen could be used as an environmental indicator species to determine if an area has high levels of acid precipitation. (f) Identify the independent variable in the investigation.
(g) Identify one variable that was not mentioned in the description above that could affect the results of the investigation. (h) Describe the relationship between average thaw depth and time since the last fire.
